Perl warning in git-svn (git v1.5.3-rc7-16-ge340d7d)

Hi,

The latest head of git gives me this when doing most operations, this
also happens with the rc7 experimental Debian package. It's annoying
because it prints this line hundreds of times for each call to 'log',
for example

"Use of uninitialized value in string eq at blah/git/git-svn line 826."

and this fixes it;

diff --git a/git-svn.perl b/git-svn.perl
