I have an answer that was helpful enough for the OP to accept, but I think the other answer is better (it includes mine too), so I want to delete mine. Is that OK?
To those who wonder why I asked:
You are free to delete your answers any time, and it is always acceptable (encouraged, even) to delete your answer if you feel other answers cover the same ground.
(The only time this is a problem, is when people decide to self-immolate and delete all their content ... aka ragequit. We have some protection in place for this now.)
