Think the problem is tracking logical directory paths following 
symlinks makes it difficult to reconstruct a relative Windows 
directory path - I like and use symlinks a lot as command line 
accessible shortcuts to directories spread all over the place 
- and shells that only track physical directory paths used to 
drive me wild, as cd dir followed by cd .. left me off in the 
wild.
