 if you insert a link in a comment, like:


 {{{
 <a href="foo" rel="bar nofollow">
 }}}

 wp_rel_nofollow_callback() turns that into:

 {{{
 <a href="foo" rel="bar nofollow" rel="nofollow">
 }}}

 Here's a correct implementation of a strip_nofollow() function:

 dofollow.php

 We'd probably want to do the same in WP, and then reverse it: add
 rel=nofollow if no rel is present, and add a nofollow to the rel if it's
 not in there already.
