 	and AUTO_DEMANGLING styles.  If expecting a function and managed
 	to demangle the funct args, then handle the LUCID_DEMANGLING,
 	ARM_DEMANGLING, and EDG_DEMANGLING styles.  Add case for local
 	class name after "Lnnn_ in HP style case. HP style too needs to
 	forget types.  _nnn is OK for HP style, so don't report failure.
