 A base feature of wordpress comment/discussion option is to put a comment
 into moderation if it contains more than x external links
 (''comment_max_links'' [http://codex.wordpress.org/Option_Reference
 option]).

 This functionality is broken because the number of external links (as
 announced in the code) is not properly calcualted.

 For example, relative links as well as links to the same page are
 calculated.

 To Fix this issue, it could be argumented that not the number of external
 links should be measured but only the number of links.

 This argumentation comes with the price that the motivation of this option
 is undermined. The motivation is to count external links because only
 external links are used in link spam. Link spam is done by spamming
 commments.

 Even when paying that price (and rendering the option pretty useless so to
 force users to use third-party tools), a bit problem is, that a plugin can
 not hook into the current implementation because the call to the
 ''comment_max_links_url'' filter does not pass the comment text.
