missed argument for entity_collection_content_form_autocomplete

Hey guy,
thank you developed this great module. But there is little issue here:

  $items['entity_collection/autocomplete/%entity_collection/%/%/%'] = array(
    'title' => 'entity_collection autocomplete',
    'page callback' => 'entity_collection_content_form_autocomplete',
    'page arguments' => array(2, 3, 4),
    'access callback' => 'entity_collection_access',
    'access arguments' => array('add content to', 2),
    'type' => MENU_CALLBACK,
    'file' => 'entity_collection.admin.inc',
  );

  $items['entity_collection/autocomplete/%entity_collection/%/%/%'] = array(
    'title' => 'entity_collection autocomplete',
    'page callback' => 'entity_collection_content_form_autocomplete',
    'page arguments' => array(2, 3, 4, 5), // <strong>Please add 5 here. you missed it</strong>
    'access callback' => 'entity_collection_access',
    'access arguments' => array('add content to', 2),
    'type' => MENU_CALLBACK,
    'file' => 'entity_collection.admin.inc',
  );

Cheers
Jackey
