0.7.13.30:
	Install faster EQUAL on simple-bit-vectors
	... word-at-a-time, not bit-at-a-time
	Frobs for correctness
	... much like one that was solved for 0.7.3.5, we must be
		careful about identifying the last word of the bit vector,
		particularly for bit-vectors whose length is divisible by
        	32^Wn-word-bits.  Less critical in this case, but we could
		still be reading into random space, even if not writing.
	Frobs for yet more speed
	... allow CMUCL to optimize ASH, as long as none of the values
		are in the danger zone.  Also reported the bug to CMUCL
		people, and it is now fixed, so when all traces of 18d
		are removed from this earth, the conditional in
		ASH-DERIVE-TYPE-AUX can go too.
