You are using toy examples. It doesn't work in real life. E.g.,
outer quotes are only removed if the whole command starts with a
quote, which is not always what you want (think about protecting a
wildcard).
Sorry, I don't have time to present examples which break, all I can
say is that I was at this impasse more than once. It's unworkable.
