Preventing repeated ‘rel=”nofollow”‘

Adding the if-statement below before line 594 of functions-formatting.php 2.0.4, will prevent the filter from adding multiple ‘rel=”nofollow”‘ to links in comments when a comment is edited, which is the current behaviour.

if (preg_match('/rel=\"nofollow\"/i', $text) == 0)

The function wp_rel_nofollow( $text ), will be as follows:

function wp_rel_nofollow( $text ) {
if (preg_match('/rel=\"nofollow\"/i', $text) == 0)
$text = preg_replace('|<a (.+?)>|i', '<a $1 rel="nofollow">', $text);
return $text;
}

Repeated rel=”nofollow” will not break your blog in any way. All it does is cause an XHTML validator to throw a warning.
