After my first reply to your posting, I've been thinking more about the 
problem you brought up of teasing apart a path in a portable way, and 
related issues like query functions.

Right now the functions that return a portion of the path are leaf(), and 
its complement, branch().

You have suggested adding root(). It seems to me the complement might also 
be useful.  Something like relative(), which returns a path with any root 
elements removed.

I'm still not set in my mind how to handle the components of roots in the 
many non-POSIX operating systems which separate the concept of 
drive/device/volume/share/host/filesystem from the concept of 
root-directory. I think the library may need the ability to extract those 
elements as separate entities, and possibly their complements.
