CONFIGURATION FILE
------------------

The Git configuration file contains a number of variables that affect
the Git commands' behavior. The `.git/config` file in each repository
is used to store the configuration for that repository, and
`$HOME/.gitconfig` is used to store a per-user configuration as
fallback values for the `.git/config` file. The file `/etc/gitconfig`
can be used to store a system-wide default configuration.

The configuration variables are used by both the Git plumbing
and the porcelains. The variables are divided into sections, wherein
the fully qualified variable name of the variable itself is the last
dot-separated segment and the section name is everything before the last
dot. The variable names are case-insensitive, allow only alphanumeric
characters and `-`, and must start with an alphabetic character.  Some
variables may appear multiple times; we say then that the variable is
multivalued.

Syntax
~~~~~~

The syntax is fairly flexible and permissive; whitespaces are mostly
ignored.  The '#' and ';' characters begin comments to the end of line,
blank lines are ignored.

The file consists of sections and variables.  A section begins with
the name of the section in square brackets and continues until the next
section begins.  Section names are case-insensitive.  Only alphanumeric
characters, `-` and `.` are allowed in section names.  Each variable
must belong to some section, which means that there must be a section
header before the first setting of a variable.

Sections can be further divided into subsections.  To begin a subsection
put its name in double quotes, separated by space from the section name,
in the section header, like in the example below:

--------
	[section "subsection"]

--------

Subsection names are case sensitive and can contain any characters except
newline and the null byte. Doublequote `"` and backslash can be included
by escaping them as `\"` and `\\`, respectively. Backslashes preceding
other characters are dropped when reading; for example, `\t` is read as
`t` and `\0` is read as `0` Section headers cannot span multiple lines.
Variables may belong directly to a section or to a given subsection. You
can have `[section]` if you have `[section "subsection"]`, but you don't
need to.

There is also a deprecated `[section.subsection]` syntax. With this
syntax, the subsection name is converted to lower-case and is also
compared case sensitively. These subsection names follow the same
restrictions as section names.

All the other lines (and the remainder of the line after the section
header) are recognized as setting variables, in the form
'name = value' (or just 'name', which is a short-hand to say that
the variable is the boolean "true").
The variable names are case-insensitive, allow only alphanumeric characters
and `-`, and must start with an alphabetic character.

A line that defines a value can be continued to the next line by
ending it with a `\`; the backquote and the end-of-line are
stripped.  Leading whitespaces after 'name =', the remainder of the
line after the first comment character '#' or ';', and trailing
whitespaces of the line are discarded unless they are enclosed in
double quotes.  Internal whitespaces within the value are retained
verbatim.

Inside double quotes, double quote `"` and backslash `\` characters
must be escaped: use `\"` for `"` and `\\` for `\`.

The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
and `\b` for backspace (BS).  Other char escape sequences (including octal
escape sequences) are invalid.


Includes
~~~~~~~~

The `include` and `includeIf` sections allow you to include config
directives from another source. These sections behave identically to
each other with the exception that `includeIf` sections may be ignored
if their condition does not evaluate to true; see "Conditional includes"
below.

You can include a config file from another by setting the special
`include.path` (or `includeIf.*.path`) variable to the name of the file
to be included. The variable takes a pathname as its value, and is
subject to tilde expansion. These variables can be given multiple times.

The contents of the included file are inserted immediately, as if they
had been found at the location of the include directive. If the value of the
variable is a relative path, the path is considered to
be relative to the configuration file in which the include directive
was found.  See below for examples.

Conditional includes
~~~~~~~~~~~~~~~~~~~~

You can include a config file from another conditionally by setting a
`includeIf.<condition>.path` variable to the name of the file to be
included.

The condition starts with a keyword followed by a colon and some data
whose format and meaning depends on the keyword. Supported keywords
are:

`gitdir`::

	The data that follows the keyword `gitdir:` is used as a glob
	pattern. If the location of the .git directory matches the
	pattern, the include condition is met.
+
The .git location may be auto-discovered, or come from `$GIT_DIR`
environment variable. If the repository is auto discovered via a .git
file (e.g. from submodules, or a linked worktree), the .git location
would be the final location where the .git directory is, not where the
.git file is.
+
The pattern can contain standard globbing wildcards and two additional
ones, `**/` and `/**`, that can match multiple path components. Please
refer to linkgit:gitignore[5] for details. For convenience:

 * If the pattern starts with `~/`, `~` will be substituted with the
   content of the environment variable `HOME`.

 * If the pattern starts with `./`, it is replaced with the directory
   containing the current config file.

 * If the pattern does not start with either `~/`, `./` or `/`, `**/`
   will be automatically prepended. For example, the pattern `foo/bar`
   becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.

 * If the pattern ends with `/`, `**` will be automatically added. For
   example, the pattern `foo/` becomes `foo/**`. In other words, it
   matches "foo" and everything inside, recursively.

`gitdir/i`::
	This is the same as `gitdir` except that matching is done
	case-insensitively (e.g. on case-insensitive file sytems)

A few more notes on matching via `gitdir` and `gitdir/i`:

 * Symlinks in `$GIT_DIR` are not resolved before matching.

 * Both the symlink & realpath versions of paths will be matched
   outside of `$GIT_DIR`. E.g. if ~/git is a symlink to
   /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git`
   will match.
+
This was not the case in the initial release of this feature in
v2.13.0, which only matched the realpath version. Configuration that
wants to be compatible with the initial release of this feature needs
to either specify only the realpath version, or both versions.

 * Note that "../" is not special and will match literally, which is
   unlikely what you want.

Example
~~~~~~~

	# Core variables
	[core]
		; Don't trust file modes
		filemode = false

	# Our diff algorithm
	[diff]
		external = /usr/local/bin/diff-wrapper
		renames = true

	[branch "devel"]
		remote = origin
		merge = refs/heads/devel

	# Proxy settings
	[core]
		gitProxy="ssh" for "kernel.org"
		gitProxy=default-proxy ; for the rest

	[include]
		path = /path/to/foo.inc ; include by absolute path
		path = foo.inc ; find "foo.inc" relative to the current file
		path = ~/foo.inc ; find "foo.inc" in your `$HOME` directory

	; include if $GIT_DIR is /path/to/foo/.git
	[includeIf "gitdir:/path/to/foo/.git"]
		path = /path/to/foo.inc

	; include for all repositories inside /path/to/group
	[includeIf "gitdir:/path/to/group/"]
		path = /path/to/foo.inc

	; include for all repositories inside $HOME/to/group
	[includeIf "gitdir:~/to/group/"]
		path = /path/to/foo.inc

	; relative paths are always relative to the including
	; file (if the condition is true); their location is not
	; affected by the condition
	[includeIf "gitdir:/path/to/group/"]
		path = foo.inc

Values
~~~~~~

Values of many variables are treated as a simple string, but there
are variables that take values of specific types and there are rules
as to how to spell them.

boolean::

       When a variable is said to take a boolean value, many
       synonyms are accepted for 'true' and 'false'; these are all
       case-insensitive.

	true;; Boolean true literals are `yes`, `on`, `true`,
		and `1`.  Also, a variable defined without `= <value>`
		is taken as true.

	false;; Boolean false literals are `no`, `off`, `false`,
		`0` and the empty string.
+
When converting a value to its canonical form using the `--type=bool` type
specifier, 'git config' will ensure that the output is "true" or
"false" (spelled in lowercase).

integer::
       The value for many variables that specify various sizes can
       be suffixed with `k`, `M`,... to mean "scale the number by
       1024", "by 1024x1024", etc.

color::
       The value for a variable that takes a color is a list of
       colors (at most two, one for foreground and one for background)
       and attributes (as many as you want), separated by spaces.
+
The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`,
`blue`, `magenta`, `cyan` and `white`.  The first color given is the
foreground; the second is the background.
+
Colors may also be given as numbers between 0 and 255; these use ANSI
256-color mode (but note that not all terminals may support this).  If
your terminal supports it, you may also specify 24-bit RGB values as
hex, like `#ff0ab3`.
+
The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`,
`italic`, and `strike` (for crossed-out or "strikethrough" letters).
The position of any attributes with respect to the colors
(before, after, or in between), doesn't matter. Specific attributes may
be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`,
`no-ul`, etc).
+
An empty color string produces no color effect at all. This can be used
to avoid coloring specific elements without disabling color entirely.
+
For git's pre-defined color slots, the attributes are meant to be reset
at the beginning of each item in the colored output. So setting
`color.decorate.branch` to `black` will paint that branch name in a
plain `black`, even if the previous thing on the same output line (e.g.
opening parenthesis before the list of branch names in `log --decorate`
output) is set to be painted with `bold` or some other attribute.
However, custom log formats may do more complicated and layered
coloring, and the negated forms may be useful there.

pathname::
	A variable that takes a pathname value can be given a
	string that begins with "`~/`" or "`~user/`", and the usual
	tilde expansion happens to such a string: `~/`
	is expanded to the value of `$HOME`, and `~user/` to the
	specified user's home directory.


Variables
~~~~~~~~~

Note that this list is non-comprehensive and not necessarily complete.
For command-specific variables, you will find a more detailed description
in the appropriate manual page.

Other git-related tools may and do use their own variables.  When
inventing new variables for use in your own tool, make sure their
names do not conflict with those that are used by Git itself and
other popular tools, and describe them in your documentation.

reset.quiet::
	When set to true, 'git reset' will default to the '--quiet' option.

include::sendemail-config.txt[]

sequence.editor::
	Text editor used by `git rebase -i` for editing the rebase instruction file.
	The value is meant to be interpreted by the shell when it is used.
	It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
	When not configured the default commit message editor is used instead.

showBranch.default::
	The default set of branches for linkgit:git-show-branch[1].
	See linkgit:git-show-branch[1].

splitIndex.maxPercentChange::
	When the split index feature is used, this specifies the
	percent of entries the split index can contain compared to the
	total number of entries in both the split index and the shared
	index before a new shared index is written.
	The value should be between 0 and 100. If the value is 0 then
	a new shared index is always written, if it is 100 a new
	shared index is never written.
	By default the value is 20, so a new shared index is written
	if the number of entries in the split index would be greater
	than 20 percent of the total number of entries.
	See linkgit:git-update-index[1].

splitIndex.sharedIndexExpire::
	When the split index feature is used, shared index files that
	were not modified since the time this variable specifies will
	be removed when a new shared index file is created. The value
	"now" expires all entries immediately, and "never" suppresses
	expiration altogether.
	The default value is "2.weeks.ago".
	Note that a shared index file is considered modified (for the
	purpose of expiration) each time a new split-index file is
	either created based on it or read from it.
	See linkgit:git-update-index[1].

include::config/ssh.txt[]

status.relativePaths::
	By default, linkgit:git-status[1] shows paths relative to the
	current directory. Setting this variable to `false` shows paths
	relative to the repository root (this was the default for Git
	prior to v1.5.4).

status.short::
	Set to true to enable --short by default in linkgit:git-status[1].
	The option --no-short takes precedence over this variable.

status.branch::
	Set to true to enable --branch by default in linkgit:git-status[1].
	The option --no-branch takes precedence over this variable.

status.displayCommentPrefix::
	If set to true, linkgit:git-status[1] will insert a comment
	prefix before each output line (starting with
	`core.commentChar`, i.e. `#` by default). This was the
	behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
	Defaults to false.

status.renameLimit::
	The number of files to consider when performing rename detection
	in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
	the value of diff.renameLimit.

status.renames::
	Whether and how Git detects renames in linkgit:git-status[1] and
	linkgit:git-commit[1] .  If set to "false", rename detection is
	disabled. If set to "true", basic rename detection is enabled.
	If set to "copies" or "copy", Git will detect copies, as well.
	Defaults to the value of diff.renames.

status.showStash::
	If set to true, linkgit:git-status[1] will display the number of
	entries currently stashed away.
	Defaults to false.

status.showUntrackedFiles::
	By default, linkgit:git-status[1] and linkgit:git-commit[1] show
	files which are not currently tracked by Git. Directories which
	contain only untracked files, are shown with the directory name
	only. Showing untracked files means that Git needs to lstat() all
	the files in the whole repository, which might be slow on some
	systems. So, this variable controls how the commands displays
	the untracked files. Possible values are:
+
--
* `no` - Show no untracked files.
* `normal` - Show untracked files and directories.
* `all` - Show also individual files in untracked directories.
--
+
If this variable is not specified, it defaults to 'normal'.
This variable can be overridden with the -u|--untracked-files option
of linkgit:git-status[1] and linkgit:git-commit[1].

status.submoduleSummary::
	Defaults to false.
	If this is set to a non zero number or true (identical to -1 or an
	unlimited number), the submodule summary will be enabled and a
	summary of commits for modified submodules will be shown (see
	--summary-limit option of linkgit:git-submodule[1]). Please note
	that the summary output command will be suppressed for all
	submodules when `diff.ignoreSubmodules` is set to 'all' or only
	for those submodules where `submodule.<name>.ignore=all`. The only
	exception to that rule is that status and commit will show staged
	submodule changes. To
	also view the summary for ignored submodules you can either use
	the --ignore-submodules=dirty command-line option or the 'git
	submodule summary' command, which shows a similar output but does
	not honor these settings.

stash.showPatch::
	If this is set to true, the `git stash show` command without an
	option will show the stash entry in patch form.  Defaults to false.
	See description of 'show' command in linkgit:git-stash[1].

stash.showStat::
	If this is set to true, the `git stash show` command without an
	option will show diffstat of the stash entry.  Defaults to true.
	See description of 'show' command in linkgit:git-stash[1].

include::submodule-config.txt[]

tag.forceSignAnnotated::
	A boolean to specify whether annotated tags created should be GPG signed.
	If `--annotate` is specified on the command line, it takes
	precedence over this option.

tag.sort::
	This variable controls the sort ordering of tags when displayed by
	linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
	value of this variable will be used as the default.

tar.umask::
	This variable can be used to restrict the permission bits of
	tar archive entries.  The default is 0002, which turns off the
	world write bit.  The special value "user" indicates that the
	archiving user's umask will be used instead.  See umask(2) and
	linkgit:git-archive[1].

transfer.fsckObjects::
	When `fetch.fsckObjects` or `receive.fsckObjects` are
	not set, the value of this variable is used instead.
	Defaults to false.
+
When set, the fetch or receive will abort in the case of a malformed
object or a link to a nonexistent object. In addition, various other
issues are checked for, including legacy issues (see `fsck.<msg-id>`),
and potential security issues like the existence of a `.GIT` directory
or a malicious `.gitmodules` file (see the release notes for v2.2.1
and v2.17.1 for details). Other sanity and security checks may be
added in future releases.
+
On the receiving side, failing fsckObjects will make those objects
unreachable, see "QUARANTINE ENVIRONMENT" in
linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
instead be left unreferenced in the repository.
+
Due to the non-quarantine nature of the `fetch.fsckObjects`
implementation it can not be relied upon to leave the object store
clean like `receive.fsckObjects` can.
+
As objects are unpacked they're written to the object store, so there
can be cases where malicious objects get introduced even though the
"fetch" failed, only to have a subsequent "fetch" succeed because only
new incoming objects are checked, not those that have already been
written to the object store. That difference in behavior should not be
relied upon. In the future, such objects may be quarantined for
"fetch" as well.
+
For now, the paranoid need to find some way to emulate the quarantine
environment if they'd like the same protection as "push". E.g. in the
case of an internal mirror do the mirroring in two steps, one to fetch
the untrusted objects, and then do a second "push" (which will use the
quarantine) to another internal repo, and have internal clients
consume this pushed-to repository, or embargo internal fetches and
only allow them once a full "fsck" has run (and no new fetches have
happened in the meantime).

transfer.hideRefs::
	String(s) `receive-pack` and `upload-pack` use to decide which
	refs to omit from their initial advertisements.  Use more than
	one definition to specify multiple prefix strings. A ref that is
	under the hierarchies listed in the value of this variable is
	excluded, and is hidden when responding to `git push` or `git
	fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
	program-specific versions of this config.
+
You may also include a `!` in front of the ref name to negate the entry,
explicitly exposing it, even if an earlier entry marked it as hidden.
If you have multiple hideRefs values, later entries override earlier ones
(and entries in more-specific config files override less-specific ones).
+
If a namespace is in use, the namespace prefix is stripped from each
reference before it is matched against `transfer.hiderefs` patterns.
For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
is omitted from the advertisements but `refs/heads/master` and
`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
"have" lines. In order to match refs before stripping, add a `^` in front of
the ref name. If you combine `!` and `^`, `!` must be specified first.
+
Even if you hide refs, a client may still be able to steal the target
objects via the techniques described in the "SECURITY" section of the
linkgit:gitnamespaces[7] man page; it's best to keep private data in a
separate repository.

transfer.unpackLimit::
	When `fetch.unpackLimit` or `receive.unpackLimit` are
	not set, the value of this variable is used instead.
	The default value is 100.

uploadarchive.allowUnreachable::
	If true, allow clients to use `git archive --remote` to request
	any tree, whether reachable from the ref tips or not. See the
	discussion in the "SECURITY" section of
	linkgit:git-upload-archive[1] for more details. Defaults to
	`false`.

uploadpack.hideRefs::
	This variable is the same as `transfer.hideRefs`, but applies
	only to `upload-pack` (and so affects only fetches, not pushes).
	An attempt to fetch a hidden ref by `git fetch` will fail.  See
	also `uploadpack.allowTipSHA1InWant`.

uploadpack.allowTipSHA1InWant::
	When `uploadpack.hideRefs` is in effect, allow `upload-pack`
	to accept a fetch request that asks for an object at the tip
	of a hidden ref (by default, such a request is rejected).
	See also `uploadpack.hideRefs`.  Even if this is false, a client
	may be able to steal objects via the techniques described in the
	"SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
	best to keep private data in a separate repository.

uploadpack.allowReachableSHA1InWant::
	Allow `upload-pack` to accept a fetch request that asks for an
	object that is reachable from any ref tip. However, note that
	calculating object reachability is computationally expensive.
	Defaults to `false`.  Even if this is false, a client may be able
	to steal objects via the techniques described in the "SECURITY"
	section of the linkgit:gitnamespaces[7] man page; it's best to
	keep private data in a separate repository.

uploadpack.allowAnySHA1InWant::
	Allow `upload-pack` to accept a fetch request that asks for any
	object at all.
	Defaults to `false`.

uploadpack.keepAlive::
	When `upload-pack` has started `pack-objects`, there may be a
	quiet period while `pack-objects` prepares the pack. Normally
	it would output progress information, but if `--quiet` was used
	for the fetch, `pack-objects` will output nothing at all until
	the pack data begins. Some clients and networks may consider
	the server to be hung and give up. Setting this option instructs
	`upload-pack` to send an empty keepalive packet every
	`uploadpack.keepAlive` seconds. Setting this option to 0
	disables keepalive packets entirely. The default is 5 seconds.

uploadpack.packObjectsHook::
	If this option is set, when `upload-pack` would run
	`git pack-objects` to create a packfile for a client, it will
	run this shell command instead.  The `pack-objects` command and
	arguments it _would_ have run (including the `git pack-objects`
	at the beginning) are appended to the shell command. The stdin
	and stdout of the hook are treated as if `pack-objects` itself
	was run. I.e., `upload-pack` will feed input intended for
	`pack-objects` to the hook, and expects a completed packfile on
	stdout.
+
Note that this configuration variable is ignored if it is seen in the
repository-level config (this is a safety measure against fetching from
untrusted repositories).

uploadpack.allowFilter::
	If this option is set, `upload-pack` will support partial
	clone and partial fetch object filtering.

uploadpack.allowRefInWant::
	If this option is set, `upload-pack` will support the `ref-in-want`
	feature of the protocol version 2 `fetch` command.  This feature
	is intended for the benefit of load-balanced servers which may
	not have the same view of what OIDs their refs point to due to
	replication delay.

url.<base>.insteadOf::
	Any URL that starts with this value will be rewritten to
	start, instead, with <base>. In cases where some site serves a
	large number of repositories, and serves them with multiple
	access methods, and some users need to use different access
	methods, this feature allows people to specify any of the
	equivalent URLs and have Git automatically rewrite the URL to
	the best alternative for the particular user, even for a
	never-before-seen repository on the site.  When more than one
	insteadOf strings match a given URL, the longest match is used.
+
Note that any protocol restrictions will be applied to the rewritten
URL. If the rewrite changes the URL to use a custom protocol or remote
helper, you may need to adjust the `protocol.*.allow` config to permit
the request.  In particular, protocols you expect to use for submodules
must be set to `always` rather than the default of `user`. See the
description of `protocol.allow` above.

url.<base>.pushInsteadOf::
	Any URL that starts with this value will not be pushed to;
	instead, it will be rewritten to start with <base>, and the
	resulting URL will be pushed to. In cases where some site serves
	a large number of repositories, and serves them with multiple
	access methods, some of which do not allow push, this feature
	allows people to specify a pull-only URL and have Git
	automatically use an appropriate URL to push, even for a
	never-before-seen repository on the site.  When more than one
	pushInsteadOf strings match a given URL, the longest match is
	used.  If a remote has an explicit pushurl, Git will ignore this
	setting for that remote.

user.email::
	Your email address to be recorded in any newly created commits.
	Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
	`EMAIL` environment variables.  See linkgit:git-commit-tree[1].

user.name::
	Your full name to be recorded in any newly created commits.
	Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
	environment variables.  See linkgit:git-commit-tree[1].

user.useConfigOnly::
	Instruct Git to avoid trying to guess defaults for `user.email`
	and `user.name`, and instead retrieve the values only from the
	configuration. For example, if you have multiple email addresses
	and would like to use a different one for each repository, then
	with this configuration option set to `true` in the global config
	along with a name, Git will prompt you to set up an email before
	making new commits in a newly cloned repository.
	Defaults to `false`.

user.signingKey::
	If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
	key you want it to automatically when creating a signed tag or
	commit, you can override the default selection with this variable.
	This option is passed unchanged to gpg's --local-user parameter,
	so you may specify a key using any method that gpg supports.

versionsort.prereleaseSuffix (deprecated)::
	Deprecated alias for `versionsort.suffix`.  Ignored if
	`versionsort.suffix` is set.

versionsort.suffix::
	Even when version sort is used in linkgit:git-tag[1], tagnames
	with the same base version but different suffixes are still sorted
	lexicographically, resulting e.g. in prerelease tags appearing
	after the main release (e.g. "1.0-rc1" after "1.0").  This
	variable can be specified to determine the sorting order of tags
	with different suffixes.
+
By specifying a single suffix in this variable, any tagname containing
that suffix will appear before the corresponding main release.  E.g. if
the variable is set to "-rc", then all "1.0-rcX" tags will appear before
"1.0".  If specified multiple times, once per suffix, then the order of
suffixes in the configuration will determine the sorting order of tagnames
with those suffixes.  E.g. if "-pre" appears before "-rc" in the
configuration, then all "1.0-preX" tags will be listed before any
"1.0-rcX" tags.  The placement of the main release tag relative to tags
with various suffixes can be determined by specifying the empty suffix
among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
are listed first, followed by "v4.8", then "v4.8-ckX" and finally
"v4.8-bfsX".
+
If more than one suffixes match the same tagname, then that tagname will
be sorted according to the suffix which starts at the earliest position in
the tagname.  If more than one different matching suffixes start at
that earliest position, then that tagname will be sorted according to the
longest of those suffixes.
The sorting order between different suffixes is undefined if they are
in multiple config files.

web.browser::
	Specify a web browser that may be used by some commands.
	Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
	may use it.

worktree.guessRemote::
	With `add`, if no branch argument, and neither of `-b` nor
	`-B` nor `--detach` are given, the command defaults to
	creating a new branch from HEAD.  If `worktree.guessRemote` is
	set to true, `worktree add` tries to find a remote-tracking
	branch whose name uniquely matches the new branch name.  If
	such a branch exists, it is checked out and set as "upstream"
	for the new branch.  If no such match can be found, it falls
	back to creating a new branch from the current HEAD.
