Comment (by jeremyfelt):

 Additional info:

 * If the `admin_email` has not been changed, you are unable to revoke
 super admin privileges on a user. This could remove the requirement to
 check `admin_user_id` or `admin_email` as that can be assumed as already
 changed.
 * `admin_email` can be changed to another user while leaving `admin_id` as
 is. `admin_id` does not prevent a super admin from being demoted.
 * If we remove the check for `$id != 0`, it is unlikely though possible
 that you end up with [http://cl.ly/image/3U3P13400e3g this screen], so we
 should leave that check there.

 [attachment:16293.4.diff] removes only the `$id != 1` check.

 I *think* the only thing up in the air with this patch is the behavior of
 the `manage_network_users` capability.
