I think for the case of CPAN we could do: 

my $escapedname=$query->escape($nodeloc); my $cpantitle= $title || $no
+deloc; my $mode=$VARS->{cpan_link_opts} || 'mode=module'; return qq[<
+a href="http://search.cpan.org/search?$mode&query=$escapedname">$cpan
+title</a>];

IMO there isnt so much need for a general solution, I dont think that many of the link types can really benefit from such tricks.
