* eval.c (Fautoload): Renamed fifth argument TYPE. Document the

	fact that (eq TYPE 'keymap) means FUNCTION will become a keymap
	when loaded.
	(Fmacroexpand): Instead of assuming that every autoload
	form with a fifth element is a macro, actually check the fifth
	element against t and `macro', which are the only values which
	denote macroness.
