fix glob descent into . and .. with GLOB_PERIOD
GLOB_PERIOD is a gnu extension, and GNU glob does not seem to honor it
except in the last path component. it's not clear whether this a bug
or intentional, but it seems reasonable that it should exclude the
special entries . and .. when walking.
changes based on report and analysis by Julien Ramseier.
