27af01d (xdiff/xprepare: improve O(n*m) performance in
xdl_cleanup_records(), 2011-08-17) was supposed to be a performance
boost only. However, it unexpectedly changed the behaviour of diff.
Revert a part of 27af01d that removes logic that mark lines as
"multi-match" (ie. dis[i] == 2). This was preventing the multi-match
discard heuristic (performed in xdl_cleanup_records() and
xdl_clean_mmatch()) from executing.

In xdl_cleanup_records(), we see O(n*m) performance, where n is the
number of records from xdf->dstart to xdf->dend, and m is the size of a
bucket in xdf->rhash (<= by mlim).
Here, we improve this to O(n) by pre-computing nm (in rcrec->len(1|2))
in xdl_classify_record().

If a file is unchanged but stat-dirty, we may erroneously
fail to apply patches, thinking that they conflict with a
dirty working tree.
This patch adds a call to "update-index --refresh". It comes
as late as possible, so that we don't bother with it for
thinks like "git rebase --abort", or when mbox-splitting
fails. However, it does come before we actually start
applying patches, meaning we will only call it once when we
start applying patches (or any time we return to "am" after
having resolved conflicts), and not once per patch.

filter-branch: Export variable `workdir' for --commit-filter
Documentation/Makefile: add *.pdf to `clean' target
Documentation: ignore *.pdf files
|
|
According to `git help filter-branch':
--commit-filter <command>
...
You can use the _map_ convenience function in this filter,
and other convenience functions, too...
...
However, it turns out that `map' hasn't been usable because it depends
on the variable `workdir', which is not propogated to the environment
of the shell that runs the commit-filter <command> because the
shell is created via a simple-command rather than a compound-command
subshell:
@SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
$(git write-tree) $parentstr < ../message > ../map/$commit ||
die "could not write rewritten commit"
One solution is simply to export `workdir'. However, it seems rather
heavy-handed to export `workdir' to the environments of all commands,
so instead this commit exports `workdir' for only the duration of the
shell command in question:
workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
$(git write-tree) $parentstr < ../message > ../map/$commit ||
die "could not write rewritten commit"

Many pathnames in a fast-import stream need to be quoted. In
particular:
1. Pathnames at the end of an "M" or "D" line need quoting
if they contain a LF or start with double-quote.
2. Pathnames on a "C" or "R" line need quoting as above,
but also if they contain spaces.
For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.
This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.
In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

Many examples of git command invocation are given in asciidoc listing
blocks, which makes them monospaced and avoids further interpretation of
special characters. Some manpages make a list of examples, like:
git foo::
Run git foo.
git foo -q::
Use the "-q" option.
to quickly show many variants. However, they can sometimes be hard to
read, because they are shown in a proportional-width font (so, for
example, seeing the difference between "-- foo" and "--foo" can be
difficult).
This patch puts all such examples into backticks, which gives the
equivalent formatting to a listing block (i.e., monospaced and without
character interpretation).
As a bonus, this also fixes an example in the git-push manpage, in which
"git push origin :::" was accidentally considered a newly-indented list,
and not a list item with "git push origin :" in it.
