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.

Displaying the SHA1 of 'their' branch (the branch being merged into
the current branch) is not nearly as friendly as just displaying
the name of that branch, especially if that branch is already local
to this repository.
git-merge now sets the environment variable 'GITHEAD_%(sha1)=%(name)'
for each argument it gets passed, making the actual input name that
resolved to the commit '%(sha1)' easily available to the invoked
merge strategy.
git-merge-recursive makes use of these environment variables when
they are available by using '%(name)' whenever it outputs the commit
identification rather than '%(sha1)'. This is most obvious in the
conflict hunks created by xdl_merge:
$ git mege sideb~1
<<<<<<< HEAD:INSTALL
Good!
=======
Oops.
>>>>>>> sideb~1:INSTALL

New and experienced Git users alike are finding out too late that
they forgot to enable reflogs in the current repository, and cannot
use the information stored within it to recover from an incorrectly
entered command such as `git reset --hard HEAD^^^` when they really
meant HEAD^^ (aka HEAD~2).
So enable reflogs by default in all future versions of Git, unless
the user specifically disables it with:
[core]
logAllRefUpdates = false
in their .git/config or ~/.gitconfig.
We only enable reflogs in repositories that have a working directory
associated with them, as shared/bare repositories do not have
an easy means to prune away old log entries, or may fail logging
entirely if the user's gecos information is not valid during a push.
This heuristic was suggested on the mailing list by Junio.
Documentation was also updated to indicate the new default behavior.
We probably should start to teach usuing the reflog to recover
from mistakes in some of the tutorial material, as new users are
likely to make a few along the way and will feel better knowing
they can recover from them quickly and easily, without fsck-objects'
lost+found features.

Extend git-branch with the following options:
git-branch -m|-M [<oldbranch>] newbranch
The -M variation is required to force renaming over an exsisting
branchname.
This also indroduces $GIT_DIR/RENAME_REF which is a "metabranch"
used when renaming branches. It will always hold the original sha1
for the latest renamed branch.
Additionally, if $GIT_DIR/logs/RENAME_REF exists, all branch rename
events are logged there.
Finally, some testcases are added to verify the new options.
