PR31314, chew crashing on use of uninitialized value

The "drop" call in wrap_comment already increments pc.  Defining DOCDD
in proto.str is a warning fix.

	PR 31314
	* chew.c (wrap_comment): Don't increment pc.
	* proto.str (DOCDD): Define.

(cherry picked from commit e175a2fc60cb9709c4461cdd8596ae05e529d67b)
