The change looks good.

An unrelated tangent, but here is a tip-of-the-day for the
approximate parser.  You could have just said

	git stash pop stash@{2.hours}

and it would have been interpreted just the same ;-)

Style: no SP between redirection operator and its target, i.e.

	echo pig >file &&

This is brittle.  If new tests are added before this, the test_tick
will give you different timestamp and this test will start failing.

Perhaps grab the timestamp out of the stash that was created, e.g.

	...
        test_tick &&
        git stash &&
        stamp=$(git log -g --format="%cd" -1 refs/stash) &&
	test_tick &&
        echo cow >file &&
        git stash &&
        git stash apply "stash@{$stamp}" &&

or something?
