The type of $user->data['user_id'] is (almost) guranteed to be integer since session::session_create() casts it to integer. The type of $row['user_id'] is only an integer if the DB driver adjusts the PHP type according to the DB type. This is only done by some of our not-so-popular DB drivers and is not the case for MySQL. As such this comparison is (almost) never true and a PM is also sent to the author itself when it is sent to a group the author is also a member of. Since this behaviour seems to have been accepted by the communty, the dead code is removed and current behaviour is kept. Also, checking this in the loop seems to be a rather bad idea.
