I'm not sure it's a bug OR a feature. More likely the
sensible way to write the program, given the original
purpose. :-)

My FSC_BASE_FILENAME program has the same problem,
simply because I use PATH_SEP to obtain the path
separator. I think it would be difficult to write
a generic routine to handle all types of path separators
properly, but you could probably write a pretty good
specific one if you were sure of the types of filenames
you would be getting. I guess FSC_BASE_FILENAME is as
good a place as any to start.
