>Description:
	I ran into this by chance and one of our users noticed it.
	When a Makefile contains several lines reading
	  MAN1=	whatever....
	of which all but the last one are ignored, I would have 
	hoped portlint to warn about.
>How-To-Repeat:
>Fix:
	Other MAN entries (ranging from 1..9 to L and N) should be
	checked as well and there may be further variables where this
	makes sense.
