Obsolete menu router item returning WSOD

One of the menu router items that forum_menu() registers is not used anymore. Moreover, it returns a WSOD when trying to access it:

  $items['admin/structure/forum/edit/%forum_term'] = array(
    'page callback' => 'forum_form_main',
    'access arguments' => array('administer forums'),
    'type' => MENU_CALLBACK,
    'file' => 'forum.admin.inc',
  );

is a left-over for what is now

  $items['admin/structure/forum/edit/forum/%forum_term'] = array(
    'title' => 'Edit forum',
    'page callback' => 'forum_form_main',
    'page arguments' => array('forum', 5),
    'access arguments' => array('administer forums'),
    'type' => MENU_CALLBACK,
    'file' => 'forum.admin.inc',
  );

A clean-up for D7 head is attached.
