	* macro.c (get_any_string): Remove the two last parameters. Replace
	references to the former expand parameter by using macro_alternate.
	Simplify loop condition for checking for end-of-string.
	(get_string): Remove redunant call to sb_skip_white.
	(do_formals): Remove two last arguments to get_any_string.
	(macro_expand): Likewise.
	(expand_irp): Likewise.
