0.8.5.44:
	SB-ACLREPL threading
	... delete erroneous previous attempt (binding specials outside
		DEFUN forms)
	... define a repl fun maker, which (a) has state in closure
		variables and (b) saves its state to said variables on
		non-local exit.
	... rearrange sb-aclrepl package manipulation a little
	... RESET-CMD now searches for the sb-impl::toplevel restart by name
	All this requires some core support
	... *REPL-FUN* is ok for stateless repls, but not for stateful ones;
		change protocol to make a repl-fun by calling
		*REPL-FUN-GENERATOR* instead (I feel a bit bad about this,
		but since this is all in the SB-IMPL:: package I don't feel
		/too/ bad about breaking the interface.  I doubt anything but
		SB-ACLREPL used it anyway)
	... rebind cl specials per TOPLEVEL so that IN-PACKAGEs don't
		collide (don't use WITH-STANDARD-IO-SYNTAX, duh)
