0.7.8.44:
	new reports and restart names trying to clarify what those
		redefine-DEFSTRUCT CERROR restarts mean (cribbing
		somewhat from CMU CL CVS)
	While I'm at it, fix the behavior of the ABORT restart in
		%REDEFINE-DEFSTRUCT, so that it leaves the system
		unaffected as one might reasonably expect. (Before,
		ABORTing then retrying an incompatible definition a
		second time would allow the incompatible definition to
		take place the second time with no error.)
	As long as I'm proof-reading restart reports, use similar
		FORMAT ~< tricks in some other restarts too.
