Note that hiding "." under Unix is only an application convention, and only
for vision. Emulating system behaviour like under windows in general purpose
routines is not a good idea.

Make a decent wrapper routine that does Fahidden on the platforms that
support it, and that masks "." on platforms that you think should.

I don't think is wise. This is presentation behaviour, and should be solved
in corresponding (G)UI components, not on the system level.
