Just a thought: a return value of nil would make it possible for
users
to opt for return-itself behaviour by using

    Filesystem.mount_point(itself = '/home/djberge/foo.txt') || itself

I have no idea which case is be more likely but it seems to me that
returning itself gives users fewer choices. It seems to me that nil
would be more consistent with the usual ruby practice.
