0.6.11.38:
	got rid of CONDITION-FUNCTION-NAME logic, since it was messy
		and it didn't work very well and, given BACKTRACE, it
		seemed mostly redundant
	bumped fasl file version since CONDITION layout changed
	renamed FIND-CALLER-NAME to FIND-CALLER-NAME-AND-FRAME
	used BREAK's *STACK-TOP-HINT* idiom in ERROR and CERROR too
	removed PRINT-SIMPLE-ERROR stuff, so that SIMPLE-ERROR just
		prints as SIMPLE-CONDITION
	WHITESPACE-CHAR-P belongs in target-char.lisp (and in SB!INT).
