[support] how to edit comment confirmation message?

[sebastian]

Hello! Good day to you all.

Line 780 of file comment.module:
Drupal 6

if ($edit['status'] == COMMENT_NOT_PUBLISHED) {
         drupal_set_message(t('Your comment has been queued for 
moderation by site administrators and will be published after approval.'));

How do I theme this message to change its out? Can't find anything on 
google.

Thanks!!

Seb.
