Thanks for beefing up the tests. It's rather unfortunate that we missed
such a severe regression.

This single-commands might be more readable using "git -C", but this
matches the existing style in the test script, so I'm OK with it either
way.

And the simplification from the prior step pays off. Looks good.

The rest of it seems pretty sensible (modulo the caveat that I don't know
remote-testgit well enough to detect anything subtle).
