mergetool: fix emerge when running in a subdirectory
Only pass the basename of the output filename when to emerge, since
emerge interprets non-absolute pathnames relative to the containing
directory of the output buffer.
When mergetool is run from a subdirectory, "ls-files -u" nicely
limits the output to conflicted files in that directory, but
we need to give the full path to cat-file plumbing to grab the
contents of stages.

to avoid <unknown> output from %b format for a commit log message
that lack any body text.
We find rename candidates by computing a fingerprint hash of
each file, and then comparing those fingerprints. There are
inherently O(n^2) comparisons, so it pays in CPU time to
hoist the (rather expensive) computation of the fingerprint
out of that loop (or to cache it once we have computed it once).
Previously, we didn't keep the filespec information around
because then we had the potential to consume a great deal of
memory. However, instead of keeping all of the filespec
data, we can instead just keep the fingerprint.
This patch implements and uses diff_free_filespec_data_large
to accomplish that goal. We also have to change
estimate_similarity not to needlessly repopulate the
filespec data when we already have the hash.
Practical tests showed 4.5x speedup for a 10% memory usage

It might be a sign of source code management gone bad, but when two branches
has diverged almost beyond recognition and time has come for the branches to
merge, the user is going to need all the help his tool can give him. Honoring
diff.renamelimit has great potential as a painkiller in such situations.
The painkiller effect could have been achieved by e.g. 'merge.renamelimit',
but the flexibility gained by a separate option is questionable: our user
would probably expect git to detect renames equally good when merging as
when diffing (I known I did).

This allows a subproject's location to be specified and stored as relative
to the parent project's location (e.g., ./foo, or ../foo). This url is
stored in .gitmodules as given. It is resolved into an absolute url by
appending it to the parent project's url when the information is written
to .git/config (i.e., during submodule add for the originator, and
submodule init for a downstream recipient). This allows cloning of the

gitweb: Remove parse_from_to_diffinfo code from git_patchset_body
In commit 90921740bd00029708370673fdc537522aa48e6f
"gitweb: Split git_patchset_body into separate subroutines"
a part of git_patchset_body code was separated into parse_from_to_diffinfo
subroutine. But instead of replacing the separated code by the call to
mentioned subroutine, the call to subroutine was placed before the separated
code. This patch removes parse_from_to_diffinfo code from git_patchset_body

because they are not POSIX-compliant. In most cases, this has been

Full rework of quote_c_style and write_name_quoted.
* quote_c_style works on a strbuf instead of a wild buffer.
* quote_c_style is now clever enough to not add double quotes if not needed.
* write_name_quoted inherits those advantages, but also take a different
set of arguments. Now instead of asking for quotes or not, you pass a
"terminator". If it's \0 then we assume you don't want to escape, else C
escaping is performed. In any case, the terminator is also appended to the
stream. It also no longer takes the prefix/prefix_len arguments, as it's
seldomly used, and makes some optimizations harder.
* write_name_quotedpfx is created to work like write_name_quoted and take
the prefix/prefix_len arguments.
Thanks to those API changes, diff.c has somehow lost weight, thanks to the
removal of functions that were wrappers around the old write_name_quoted
trying to give it a semantics like the new one, but performing a lot of
allocations for this goal. Now we always write directly to the stream, no
intermediate allocation is performed.
As a side effect of the refactor in builtin-apply.c, the length of the bar
graphs in diffstats are not affected anymore by the fact that the path was
clipped.

functions.

Added example hook script to save/restore permissions/ownership.
Usage info is emebed in the script, but the gist of it is to run the script
from a pre-commit hook to save permissions/ownership data to a file and check
that file into the repository. Then, a post_merge hook reads the file and
updates working tree permissions/ownership. All updates are transparent to
the user (although there is a --verbose option). Merge conflicts are handled
in the "read" phase (in pre-commit), and the script aborts the commit and
tells you how to fix things in the case of a merge conflict in the metadata
file. This same idea could be extended to handle file ACLs or other file
metadata if desired.

In POSIX 1003.2 regular expressions, the star (*), is not an wildcard
meaning "match everything", it matches 0 or more matches of the atom
preceding it.
So to match "refs/heads/bw/topic-branch", the matcher should be written
as "refs/heads/bw/.*" to match "refs/heads/bw/" and everything after it.
This moves "shift" out of the argument processing "case". It also

EOF, and avoids to call strbuf_getline when it's in EOF state.
Also no longer automagically strbuf_release the buffer, it's counter
