Loop unroll fixes

[David Edelsohn]

	Zoltan repeatedly posted messages at various intervals asking
about the patch.  My private communication only followed up after each of
his repeated public requests.

	I do not accept your statement that the patch and its lack of
attention was secret.  I feel like you are trying to blame the victim.
Maybe that's just your reaction to my forcing the issue after months of
frustration.
