You're right, of course.  I'll get back to them at some point.

For instance:

>>> import posixpath
>>> posixpath.normpath('/..')
'/..'

I would have thought '/' would be a better result to return.  My
impression was that normpath is used to tell whether two paths are
actually the same, and if that's the case, its current behaviour is
going to give false negatives.  On the other hand, the code seems to
explicitly ignore multiple leading /'s, and that will also give some
false mismatches, so I must be confused somewhere...
