Modified files:
	cm3/m3-sys/m3back/src/: Wrx86.m3 

Log message:
	restore losting cleanup: THEN goes at end of line
	and go beyond that: factor common code into a function (original
	authors seemed very keen on manual inlining, which is kind of nice,
	but leads to a lot of duplicate code; we should strongly consider
	adding inlining in m3back)
	simple guard against a form of overflow that I have trouble
	believing is possible, but the guard is super cheap
