It is $gmane/91316, Message-ID: <20080804050247.GA13539@toroid.org>

After queueing it, I actually had to revert it, because it seems to break
git-svn (t9106-git-svn-commit-diff-clobber.sh, test #8), and I am about to
go to bed.  If you did not see the same breakage with your patch that does
not "fix" delete, it could be that the git-svn uses some of the resources
that are released by the delete actually doing what it is asked to do.

Yes, @vars would be interpreted in scalar context, which certainly isn't
the intended effect.
