This patch allows post-review to support git proper.
Manually tested with basic git repositories.

I don't have an ancient version of git svn on hand, so I couldn't test whether the check I added for svn-remote.svn.url is sufficient or necessary to prove something is a git-svn repository.

  1. Awesome! Thanks for doing this. Committed with minor stylistic changes (blank lines, word wrap) as r1677.
    
    By the way, you're the 100th contributor (in terms of committed contributions).
