Thanks. It is good that you avoided the common pitfall of attempting

	GIT_EDITOR=... test_must_fail git commit -c $head    ;# WRONG

but do we assume everybody has "env"?

To be portable, we can do this instead.

	(
		GIT_EDITOR=... &&
        	export GIT_EDITOR &&
                test_must_fail git commit -c $head
	)
