Heh, silly me. Yes, we _could_ parse and strip "\ " into " " if we wanted to, but we can just give "\ " and let fnmatch(3) do its thing, and that is the right thing to do for a rare corner case like this (i.e. deliberate trailing spaces).

So I think I understand your reasoning, and I agree with it.
