Incorrect use of hook_js_alter()

I was using the Advanced Aggregation module, and found a small bug in the implementation of hook_add_js(): it does not use the $javascript as a reference, so the JavaScript is never added when the Advanced Aggregation is enabled.

The correct implementation should be:

/**
 * Implements hook_js_alter().
 */
function clientside_validation_js_alter(&$javascript) {
  $clientside_validation_settings = &drupal_static('clientside_validation_settings', array());
  if (isset($clientside_validation_settings['clientsideValidation'])) {
    foreach ($clientside_validation_settings['clientsideValidation']['forms'] as $form_id => $settings) {
      $stripped_form_id = $form_id;
      $matches = array();
      preg_match(' /.*?(--(\d)*)/', $form_id, $matches);
      if (isset($matches[1])) {
        $stripped_form_id = str_replace($matches[1], '', $form_id);
      }
      if ($stripped_form_id != $form_id) {
        $clientside_validation_settings['clientsideValidation']['forms'][$form_id] = $clientside_validation_settings['clientsideValidation']['forms'][$stripped_form_id];
        $clientside_validation_settings['clientsideValidation']['groups'][$form_id] = $clientside_validation_settings['clientsideValidation']['groups'][$stripped_form_id];
      }
    }
  }
  $javascript = drupal_add_js($clientside_validation_settings, 'setting');

}
