0.8.0.80:
	PRINT-UNREADABLE-OBJECT isn't specified to do anything nice
		with pprint logical blocks, and it's hard to do
		anything nice without surprising the user, and (as
		pointed out by Antonio Martinez) it's specifically
		not supposed to do some of the whitespace stuff it was
		doing. So just ignore any pretty-streamness and do
		entirely physical output.
	tweaked ENCAPSULATE logic so that BACKTRACE reporting of
		TRACEd functions will be slightly less obscure:
			1: (.... )
		instead of
			1: ("varargs entry for #'(LAMBDA (&REST SB!INT:ARG-LIST) ...)"
			    ...)
	ruthlessly plundered CMU CL CVS and Gerd's emailed
		expertise for %NO-PRIMARY-METHOD .ARGS. code
