0.9.2.40:

	added scripts to impose whitespace canonicalization
	added scripts to check that sources haven't drifted away from
		canonical whitespacing (as when someone doesn't use
		emacs' INDENT-TABS-MODE=NIL...)
	(Note that the scripts include an annoying level of "echo"-ish
		commands which should probably be removed once things seem
		to be working OK for everyone.)
	(Something about huge touch-every-file "cvs commit" of
		canonicalized-whitespace versions of all sources is
		clashing with my flaky internet connection, so there may
		be some further delay in committing the result of running
		the scripts.)
