OK, I have fixed the problem. While your patch got close, it is best to
fix the problem in trim_trailing_separator() rather than above.
Tom already fixed the Unix case by preventing a path of '/' from being
stripped. This patch prevents c:/ and //network/ from being stripped
too. (Tom already mentioned Win32 would need work.)
