devel_generate_content_add_node() in devel_generate/devel_generate.inc: wrong @param documentation

The function currently is documented as:

/**
 * Create one node. Used by both batch and non-batch code branches.
 *
 * @param $num
 *   array of options obtained from devel_generate_content_form.
 */
function devel_generate_content_add_node(&$results) {
  $node = new stdClass();
  $node->nid = NULL;

and should be documented as:

/**
 * Create one node. Used by both batch and non-batch code branches.
 *
 * @param $results
 *   array of options obtained from devel_generate_content_form. If you call
 *   this function directly, $results should contain at the very least:
 *     node_types => an associative array of node type machine names
 *     users => an array of UIDs
 *     title_length => max number of words in titles, for example 4.
