	Untabification
	... tabs in source code in general are Evil Bad and Wrong, but in
		strings they are especially so in the context of portable
		ANSI Common Lisp, since #\Tab is not a standard character.
	... remove all tabs in strings in the source code, and write some
		defensive code to prevent them from creeping back in again.
	... one or two other whitespacey changes.
