IMHO, this is one of those cases where "Be liberal in what you accept
and strict in what you emit" applies strongly. New filesystems should
probably always emit "." and ".." in that order with sane behavior,
and new programs should probably be able to handle it if they don't. I
would add ".." and "." to squashfs, just so that it acts like the rest
of the filesystems on the planet, even if it has to emulate them
internally. OTOH, I think that the default behavior of find is broken
and should probably be fixed, maybe by making the default use the full
readdir and optionally allowing a -fast option that optimizes the
search using such tricks.
Note that Linux always accepts . and .. so it's just a matter of making
them appear in readdir.
