	I've come to suspect that the debugger/restart/QUIT problem
		has to do with the same closure/component bug I
		fixed above, except for closures over NLXs instead
		of over LAMBDA-VARs. So I'd like to generalize the
		LAMBDA-REFERS-TO-VARS fix to deal with NLXs as well.
		In preparation for that...
	...merged LAMBDA-REFERS-TO-VARS and LAMBDA-CALLS into
		LAMBDA-CALLS-OR-CLOSES
