Hmm, why does this additional test fail only under prove but pass
without it?

This is more about coding discipline than style, but piping grep
output to sed is wasteful. "sed -ne '/^GIT_/s/=.*//p'" or something
like that, perhaps?
I wondered what happens if the user has an unrelated stray variable
whose name happens to begin with GIT_ in her environment, but it
turns out that we cleanse them in test-lib.sh fairly early, so that
would be fine. You need to tighten your "grep" pattern, though.
