I suppose you could do both $line and $stat
and the fix would only work when it's on a
single line.

Perhaps something like this would work:

	if ($line =~ /whatever/ ||
	    (defined($stat) && $stat =~ /whatever/)) {
		if (WARN(...) &&
		    $fix) {
			fixed[$fixlinenr] =~ s/whatever/appropriate/;
		}
	}

No worries about getting 'round the the list.
It'll get got eventually.
