		The expression -(-X+Y)+Z was transformed into X+(Y+Z) because when
		Y and Z were put together only the flags immediately in front of them
		were carried along. Any flags on the plus node above the Y must be
		XORed together with Y's flags to get the new flags for Y in the
		new expression. Also routine STPRECLUDE was reorganized since
		HASHIT should not be called twice.
