Well spotted.  test_must_fail being a shell function, not a command,
we shouldn't have used the "VAR=val cmd" one-shot environment
assignment for portability.

Even though this happens to be the last test in the script, using
test_set_editor to permanently affect the choice of editor for tests
that follow is not generally a good idea.  It would be safer to do
this, I would have to say:

		git commit -a -m "submodule commit"
	) &&
        (
		GIT_EDITOR=cat &&
                export GIT_EDITOR &&
                test_must_fail git commit -a -v 2>err
	) &&
        test_i18ngrep "Aborting ..."

Thanks.
