filter-branch: return to original dir after filtering
The first thing filter-branch does is to create a temporary
directory, either ".git-rewrite" in the current directory
(which may be the working tree or the repository if bare),
or in a directory specified by "-d". We then chdir to
$tempdir/t as our temporary working directory in which to run
tree filters.
After finishing the filter, we then attempt to go back to
the original directory with "cd ../..". This works in the
.git-rewrite case, but if "-d" is used, we end up in a
random directory. The only thing we do after this chdir is
to run git-read-tree, but that means that:
1. The working directory is not updated to reflect the
filtered history.
2. We dump random files into "$tempdir/.." (e.g., if you
use "-d /tmp/foo", we dump junk into /tmp).
Fix it by recording the full path to the original directory
and returning there explicitly.
