Yeah, I accidentally was relying on undefined-translates-to-empty, which breaks under set -u. I can duplicate the precise error, and your fix below is exactly how I fixed it too, before seeing you posted the same fix.

Nah, please take full credit for it. It is more work to test the result of the change than just running a grep and coming up with "I wonder if this would work...".

Yeah, neither my fix (which was only trying to fix the problems I introduced in git-prompt.sh) nor Ville's fix (which was focused on git-completion.bash) caught that one.
