This does not work on Windows. Basically paths in windows
cannot end in row of dots. The dots are silently ignored.

This does work, but Cygwin's path handling code understands
only ".." and "." . If it get three dots in a raw and they
appear before the last '/' char, Cygwin returns ENOENT.

I looked in the code 2 months ago so I may miss some of
the details - please, correct me if I am wrong.

I found this in august and changed the code (normalize_posix_path)
to allow path components starting with multiple dots but I havent
sent the pathc since i had some doubts on how to implement
this properly for UNC paths - the path handling code is
the same. If someone is interested to look at it and discuss
I will be happy to send it.
