Issue an error when . (dot) is invoked without a filename. The synopsis
is just ". file" according to POSIX, however many other shells allow arguments to be passed after the file. For compatibility (we even use that feature in buildworld) additional arguments are not considered to be an error, even though this shell does not do anything with the arguments at all.
