Using a buffer limited to 2048 is unnecessarily limiting. Switch to
using a string buffer to read in stdin for annotation.

Introduce a --annotate-stdin that is functionally equivalent of --stdin.
--stdin does not behave as --stdin in other subcommands, such as
pack-objects whereby it takes one argument per line. Since --stdin can
be a confusing and misleading name, rename it to --annotate-stdin.
This change adds a warning to --stdin warning that it will be removed in
the future.

"git fetch" without the "--update-head-ok" option ought to protect
a checked out branch from getting updated, to prevent the working
tree that checks it out to go out of sync. The code was written
before the use of "git worktree" got widespread, and only checked
the branch that was checked out in the current worktree, which has
been updated.

"git worktree add" showed "Preparing worktree" message to the

Some users or scripts will pipe "git diff"
output to "git apply" when replaying diffs
or commits. In these cases, they will rely
on the return value of "git apply" to know
whether the diff was applied successfully.
However, for empty commits, "git apply" will
fail. This complicates scripts since they
have to either buffer the diff and check
its length, or run diff again with "exit-code",
essentially doing the diff twice.
Add the "--allow-empty" flag to "git apply"
which allows it to handle both empty diffs
and empty commits created by "git format-patch
--always" by doing nothing and returning 0.
Add tests for both with and without --allow-empty.

Because `sed` is line-oriented, for ease of implementation, when
chainlint.sed encounters an opening subshell in which the first command
is cuddled with the "(", it splits the line into two lines: one
containing only "(", and the other containing whatever follows "(".
This allows chainlint.sed to get by with a single set of regular
expressions for matching shell statements rather than having to
duplicate each expression (one set for matching non-cuddled statements,
and one set for matching cuddled statements).
However, although syntactically and semantically immaterial, this
transformation has no value to test authors and might even confuse them
into thinking that the linter is misbehaving by inserting (whitespace)
line-noise into the shell code it is validating. Moreover, it also
allows an implementation detail of chainlint.sed to seep into the
chainlint self-test "expect" files, which potentially makes it difficult
to reuse the self-tests should a more capable chainlint ever be
developed.
To address these concerns, stop splitting cuddled "(..." into two lines.
Note that, as an implementation artifact, due to sed's line-oriented
nature, this change inserts a blank line at output time just before the
"(..." line is emitted. It would be possible to suppress this blank line
but doing so would add a fair bit of complexity to chainlint.sed.
Therefore, rather than suppressing the extra blank line, the Makefile's
`check-chainlint` target which runs the chainlint self-tests is instead
modified to ignore blank lines when comparing chainlint output against
the self-test "expect" output. This is a reasonable compromise for two
reasons. First, the purpose of the chainlint self-tests is to verify
that the ?!AMP?! annotations are being correctly added; precise
whitespace is immaterial. Second, by necessity, chainlint.sed itself
already throws away all blank lines within subshells since, when
checking for a broken &&-chain, it needs to check the final _statement_
in a subshell, not the final _line_ (which might be blank), thus it has
never made any attempt to precisely reproduce blank lines in its output.

When checking for broken a &&-chain, chainlint.sed knows that the final
statement in a subshell should not end with `&&`, so it takes care to
make a distinction between the final line which is an actual statement
and any lines which may be mere comments preceding the closing ')'. As
such, it swallows comment lines so that they do not interfere with the
&&-chain check.
However, since `sed` does not provide any sort of real recursion,
chainlint.sed only checks &&-chains in subshells one level deep; it
doesn't do any checking in deeper subshells or in `{...}` blocks within
subshells. Furthermore, on account of potential implementation
complexity, it doesn't check &&-chains within `case` arms.
Due to an oversight, it also doesn't swallow comments inside deep
subshells, `{...}` blocks, or `case` statements, which makes its output
inconsistent (swallowing comments in some cases but not others).
Unfortunately, this inconsistency seeps into the chainlint self-test
"expect" files, which potentially makes it difficult to reuse the
self-tests should a more capable chainlint ever be developed. Therefore,
teach chainlint.sed to consistently swallow comments in all cases.

The purpose of chainlint is to highlight problems it finds in test code
by inserting annotations at the location of each problem. Arbitrarily
eliding bits of the code it is checking is not helpful, yet this is
exactly what chainlint.sed does by cavalierly and unnecessarily dropping
the here-doc operator and tag; i.e. `cat <<TAG` becomes simply `cat` in
the output. This behavior can make it more difficult for the test writer
to align the annotated output of chainlint.sed with the original test
code. Address this by retaining here-doc tags.

Tighten here-doc recognition to prevent it from being fooled by text
which looks like a here-doc operator but happens merely to be the
content of a string, such as this real-world case from t7201:
echo "<<<<<<< ours" &&
echo ourside &&
echo "=======" &&
echo theirside &&
echo ">>>>>>> theirs"
This problem went unnoticed because chainlint.sed is not a real parser,
but rather applies heuristics to pretend to understand shell code. In
this case, it saw what it thought was a here-doc operator (`<< ours`),
and fell off the end of the test looking for the closing tag "ours"
which it never found, thus swallowed the remainder of the test without
checking it for &&-chain breakage.
