Nice. I did
$ git grep -e 'for [a-z0-9_]* in ' contrib/completion/
and wondered why other hits were OK. The completion one seems to
have "emulate" all over the place to hide zsh-ness from functions it
borrows from git-completion.bash, but git-prompt side seems to lack
necessary "compatibility" stuff.

Very well said.

Thanks.
By the way, I notice that the title of the patch talks about
"completion", but this is about a prompt. It needs to be updated in
a future iteration.
