Admin area only shows 5 notifications

In Admin - users - notifications the text states:

The following table shows all users that have notifications enabled.

However, in the notifiy.inc code (line 87) there is LIMIT 5:

$result = db_query('SELECT u.uid, u.name, u.mail, n.* FROM {users} u LEFT JOIN {notify} n ON u.uid = n.uid WHERE n.status = 1 AND u.status = 1 ORDER BY u.name LIMIT 5');

Hence only 5 notifications are acutally displayed.

This behaviour is confusing and should be changed to show all notifications in a multi page layout.
