Would this actually work?

input		$n != n		$n != N		action (-a)	action (-o)
---------------------------------------------------------------------------
<not N>		true		true		exit		exit
n		false		true		rm		exit
N		true		false		rm		exit


The new statement seems wrong. The fact that the original statement had the
logic inverted still remains. It should be exit if ($n==n || $n==N).
