Does it work on all platforms, e.g. on Windows, too? I see "grep" there which does hopefully not call a Unix command...
Yes, it works, this is not grep but "git log --grep", so if you have a working git installation then it should work.
Also this patch just adds another version of this command, that searches for checkouts with the svn protocol.
The original version searches for a https protocol.
@dmoore: I doubt this patch will fix it. I'll investigate, because I'm affected too...
