to implement merging the named commit to the current branch.
This hopefully would make "git merge" usable as the first class
UI instead of being a mere backend for "git pull".
Most notably, $commit above can be any committish, so you can
say for example:
git merge js/shortlog~2
to merge early part of a topic branch without merging the rest
of it.
A custom merge message can be given with the new --message=<msg>
parameter. The message is prepended in front of the usual
"Merge ..." message autogenerated with fmt-merge-message.
As discussed on git mailing list let's teach the reader about
the possiblity to have automatically signed off the commit running
the git-commit -s command

do_for_each_ref: perform the same sanity check for leftovers.
An earlier commit b37a562a added a check to see if the ref
points at a valid object (as a part of 'negative ref' support
which we currently do not use), but did so only while iterating
over both packed and loose refs, and forgot to apply the same
check while iterating over the remaining ones.
We might want to replace the "if null then omit it" check with
"eh --- what business does a 0{40} value have here?" complaint
later since we currently do not use negative refs, but that is
a separate issue.
For one, the documentation invalidly claimed that the paths have to be
absolute when that's not the case and in fact there is a very valid reason
not to use absolute paths (documented the reason as well).

Ok, this is a _really_ stupid case, and I don't think it matters, but hey,
we should never SIGSEGV.
Steps to reproduce:
mkdir duh
cd duh
git init-db
git-fmt-merge-msg < /dev/null
will cause a SIGSEGV in cmd_fmt_merge_msg(), because we're doing a
strncmp() with a NULL current_branch.
And yeah, it's an insane schenario, and no, it doesn't really matter. The
only reason I noticed was that a broken version of my "git pull" into an
empty directory would cause this.
This silly patch just replaces the SIGSEGV with a controlled exit with an

Run "git repack -a -d" once more at end, if there's 1MB or more of not-packed data.
Although I converted upstream coreutils to git last month, I just
reconverted coreutils once again, as a test, and ended up with a
git repository of about 130MB (contrast with my packed git repo of
size 52MB). That was because there were a lot of commits (but < 1024)
after the final automatic "git-repack -a -d".
Running a final
git-repack -a -d && git-prune-packed
cut the final repository size down to the expected size.
So this looks like an easy way to improve git-cvsimport.
Just run "git repack ..." at the end if there's more than
some reasonable amount of not-packed data.
My choice of 1MB is a little arbitrarily. I wouldn't mind missing
the minimal repo size by 1MB. At the other end of the spectrum,
it's probably not worthwhile to pack everything when the total
repository size is less than 1MB.
Here's the patch:

There was a bug in dcommit (and commit-diff) which caused deltas

in a repository, and not the revision we are diffing (the tree)
against locally.
This bug can cause recent changes to the svn repository to be
silently clobbered by git-svn if our repository is out-of-date.

The same change as the previous. It is rather sad that commit log
message parser gives list of chomped lines while tag message parser
gives unchomped ones.
gitweb: protect blob and diff output lines from controls.
This revealed that the output from blame and tag was not chomped
properly and was relying on HTML output not noticing that extra
whitespace that resulted from the newline, which was also fixed.
Just make it take over blame's place. Documentation and command
have all stopped mentioning "git-pickaxe". The built-in synonym
is left in the command table, so you can still say "git pickaxe",
but it probably is a good idea to retire it as well.
Otherwise, commit log template would get the remainder of the
filename start on a new line unquoted and the log gets messed
up.
I initially considered using the full quote_c_style(), but the
output from the command is primarily for human consumption so
chose to leave other control characters and bytes with high-bits
unmolested.
Replace "gitweb diff header" with its full sha1 of blobs and replace
it by "git diff" header and extended diff header. Change also somewhat
highlighting of diffs.
Added `file_type_long' subroutine to convert file mode in octal to
file type description (only for file modes which used by git).
Changes:
* "gitweb diff header" which looked for example like below:
file:_<sha1 before>_ -> file:_<sha1 after>_
where 'file' is file type and '<sha1>' is full sha1 of blob is
changed to
diff --git _a/<file before>_ _b/<file after>_
In both cases links are visible and use default link style. If file
is added, a/<file> is not hyperlinked. If file is deleted, b/<file>
is not hyperlinked.
* there is added "extended diff header", with <path> and <hash>
hyperlinked (and <hash> shortened to 7 characters), and <mode>
explained: '<mode>' is extended to '<mode> (<file type description>)',
where added text is slightly lighter to easy distinguish that it
was added (and it is difference from git-diff output).
* from-file/to-file two-line header lines have slightly darker color
than removed/added lines.
* chunk header has now delicate line above for easier finding chunk
boundary, and top margin of 2px, both barely visible.

A forked project is defined to be $projname/$forkname.git for
$projname.git; the code did not check this correctly and mistook
$projname/.git to be a fork of itself. This minimally fixes the
breakage.
Also forks were not checked when index.aux file was in use.
Listing the forked ones in index.aux would show them also on the
toplevel index which may go against the hierarchical nature of
forks, but again this is a minimal fix to whip it in a better
shape suitable to be in the 'master' branch.
Apparently this code was never tested without "forks". check-feature
returns a one-element list (0) when disabled, and assigning that to a
scalar variable made it to be called in a scalar context, which meant
my $check_forks = gitweb_check_feature("forks") were always 1!

Take --git-dir into consideration during bash completion.
If the user has setup a command line of "git --git-dir=baz" then
anything we complete must be performed within the scope of "baz"
and not the current working directory.
This is useful with commands such as "git --git-dir=git.git log m"
to complete out "master" and view the log for the master branch of
the git.git repository. As a nice side effect this also works for
aliases within the target repository, just as git would honor them.
Unfortunately because we still examine arguments by absolute position
in most of the more complex commands (e.g. git push) using --git-dir
with those commands will probably still cause completion to fail.

Also this fixes -C and -C -C (aka find-copies-harder) logic; in
