Aggregator forms error aggregator/edit/FID

In the new version, aggregator_menu() says:

  $items['admin/content/aggregator/edit/feed/%aggregator_feed'] = array(
    'title' => 'Edit feed',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('aggregator_form_feed', 5),
    'access arguments' => array('administer news feeds'),
    'type' => MENU_CALLBACK,
  );

But the function aggregator_form_feed() takes $edit as an argument.

  function aggregator_form_feed($edit = array('refresh' => 900, 'title' => '', 'url' => '', 'fid' => NULL)) {

If I understand the new menu system correctly, 'page arguments' => array('aggregator_form_feed', 5), means "Send arg(5) [the feed id] to the function aggregator_form_feed()." Since that function is expecting the $edit array(), the page loads an empty form.

Attached patch corrects the behavior by rewriting:

  function aggregator_form_feed($fid, $edit = array('refresh' => 900, 'title' => '', 'url' => '', 'fid' => NULL)) {

But I'm not entirely sure this is the proper fix, as $fid is never invoked with the function. But it works.

Marking 'critical' because it is a total failure of the function.
