0.8.3.20:
	Fixed bug revealed by PFD in *.26:
	... (FLOAT X) should be transformed to guard against X already
		being a float, in which case no coercion should occur.
	Minor adjustments:
	... tighten up the type of RANDOM;
	... textual frobs around RANDOM area.
	(there's an extremely strange bug in RANDOM on the powerpc,
	which I haven't yet logged but will do if I can't figure out
	what's going on)
