Distinguish no directive present from unknown directive

Distinguish the case of no directive present (D_none) from the case of
an unknown specified directive (D_unknown).  This is reflected in
different error messages.

Furthermore, change the special case symbols to lower case in case we
ever have a directive called [none] or [unknown].
