I think the thing we need to fix is that mk is ignoring an assignment  
if a system variable is already defined in the environment. However,  
this doesn't apply to normal variables:

	term% cat mkfile
	x=3
	default:V:
		echo $x
	term% mk
	echo 3
	3
	term% x=4 mk
	echo 3
	4
	term% ed - mkfile
	1d
	w
	q
	term% x=4 mk
	echo $x
	4
	term%
