I suspect that it makes sense to replace the "git stash" we see
below with something like this:

	test_must_fail git commit -m should fail &&
	echo "git stash <git@stash>" >expect &&
	echo >2 &&
	git stash &&
	git show -s --format="%(authorname) <%(authoremail)>" refs/stash >actual &&
	test_cmp expect actual

That is

 - we make sure "commit" would not go through, to make sure our
   preparation to unset environment variables was sufficient;

 - we make sure "stash" does succeed (which is the primary thing you
   are interested in);

 - we make sure the resulting "stash" is not created under our
   default identity but under our fallback one.
