Finish tridge's patch as referenced here :
make sure we don't allow the creation of directories containing
wildcard characters. I've only put this in mkdir at the moment, but I
suspect this will apply to all places that can create new filenames.
We need to allow the opening of existing filenames that contain
wildcards, but not allow the creation of new ones.
Jeremy.
