The interesting thing is that I can see a need for a generic path library
(filesystem-independent). It even makes perfect sense for this library to be
templated on the character type (because the operations do not depend on a
specific type) and if I squint just right I see some benefits in adding a
'class Tr = path_traits<Ch>' parameter that will supply the path separator
character and the escape character (if any).

However I don't see how such a generic path library can be separated from
the filesystem code. The generic grammar is simply not expressive enough to
handle all native path quirks.
