The function xdl_refine_conflicts() tries to break down huge
conflicts by doing a diff on the conflicting regions. However,
this does not make sense when one side is empty.
Worse, when one side is not only empty, but after EOF, the code
accessed unmapped memory.
Noticed by Luben Tuikov, Shawn Pearce and Alexandre Julliard, the
latter providing a test case.

We have less code to worry about now. As a bonus, --revision
can be used to reliably skip parts of history whenever fetch is
run, not just the first time. I'm not sure why anybody would
want to skip history in the middle, however...
For people (nearly everyone at the moment) without the
do_switch() function in their Perl SVN library, the entire tree
must be refetched if --follow-parent is used and a parent is
found. Future versions of SVN will have a working do_switch()
function accessible via Perl.
Accessing repositories on the local machine (especially file://
ones) is also slightly slower as a result; but I suspect most
git-svn users will be using it to access remote repositories.

Now that git-merge knows how to use the pull.{twohead,octopus}

If git-merge is invoked without a strategy argument it is probably
being run as a porcelain-ish command directly and is not being run
from within git-pull. However we still should honor whatever merge
strategy the user may have selected in their configuration, just as
`git-pull .` would have.

If a three-way merge in git-rebase generates a conflict then we
should take advantage of git-merge-recursive's ability to include
the branch name of each side of the conflict hunk by setting the
GITHEAD_* environment variables.
In the case of rebase there aren't really two clear branches; we
have the branch we are rebasing onto, and we have the branch we are
currently rebasing. Since most conflicts will be arising between
the user's current branch and the branch they are rebasing onto
we assume the stuff that isn't in the current commit is the "onto"
branch and the stuff in the current commit is the "current" branch.
This assumption may however come up wrong if the user resolves one
conflict in such a way that it conflicts again on a future commit
also being rebased. In this case the user's prior resolution will
appear to be in the "onto" part of the hunk.

To help correctly log actions caused by porcelain which invoke
git-reset directly we should honor the setting of GIT_REFLOG_ACTION

Signed-off-by: Junio C Hamano <junkio@cox.net>
Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code
needed to hand it to other porcelain and plumbing alike to
ensure the reflog contained the top-level user action and
not the lower-level actions it invoked.
At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION
environment variable.

Following advice from CGI(3pm) man page, precompile all CGI routines
for mod_perl, in the BEGIN block.
If you want to compile without importing use the compile() method
instead:
use CGI();
CGI->compile();
This is particularly useful in a mod_perl environment, in which you
might want to precompile all CGI routines in a startup script, and then
import the functions individually in each mod_perl script.

Junio asked for a 'git gc' utility which users can execute on a
regular basis to perform basic repository actions such as:
* pack-refs --prune
* reflog expire
* repack -a -d
* prune
* rerere gc
So here is a command which does exactly that. The parameters fed
to reflog's expire subcommand can be chosen by the user by setting
configuration options in .git/config (or ~/.gitconfig), as users may
want different expiration windows for each repository but shouldn't
be bothered to remember what they are all of the time.

Recent "git push" keeps transferred objects packed much more aggressively
than before. Monitoring output from git-count-objects -v for number of

After checking to see if the commit message already has the target
signed-off-by (for example in --amend commits), this patch generates a
signed off by line from the repository owner and adds it to the commit
message.
Based on Johannes Schindelin's earlier patch to perform the same
function.
Originally, this was done in the pre-commit hook but Junio pointed out
that the commit-msg hook allows the message to be edited. This has the
aditional advantage that the commit-msg hook gets passed the name of the
message file as a parameter, so it doesn't have to figure out GIT_DIR for
itself.
