positively mark equates and sets which are located
	i.e. they reference addresses. So that $xqt_fp and
	$xqt_i can tell the difference between between
	renamed variables and immediate values

	the positive mark is 128 OR the location counter byte
	in the label, so even locator zero without relocation
	is identifiable. Using the byte to select a locator
	is AND 127

	stop dynamic labels which reference external labels
	from getting compressed out before their macro level
	is compressed out

	stop load_name() accidentally loading "names" which
	start with digits, so it becomes easier to tell
	if a label has been encountered

	fix all the tackier problems in the algorithmic parts
	$xqt_fp and $xqt_i. Recognise if load_name has loaded
	a name or not. Do not analyse any sub-expression with
	unary * because redirection expressions can be left to
	assembly and link
