[wp-hackers] WordPress 3 - comment_form hooks

[Andrew Nacin]

What are you trying to detect, when, and why? If you want to know whether
the hook was fired, you can use did_action(). If you want to know whether
the new comment_form exists, try checking if comment_form exists. If you
want to actually attach onto the comment_form action, then simply do so.
