Log message:
	also fix mod where inputs are minimum and negative
	Modula-3 mod (as opposed to every other programming
	language) is always supposed to have the sign
	of its second input, or be 0
	However it was backwards, depending on
	compiler and optimizer (optimizer tends to *fix* the bug)
	
	test code included, much cleaner this time
