	Fix for PEEK-CHAR: whitespace means "according to the
	readtable", not "static list of characters"
	... but that's complicated for efficiency: we need WHITESPACEP
		defined before peek-char so that it can be expanded
		inline
	... so move peek-charish things into a new later file
	... delete unused-by-core WHITESPACE-CHAR-P, and adjust
		contribs to accomodate this
	... also add #\page to sb-aclrepl's static whitespace characters
