function diff_field_diff_view($items, $context) {

  // Prevent unnecessary rendering of the field. This also prevents issues
  // where field_view_field() will use a language fallback for display that
  // may not match the requested diff comparison language.
  if (!$items) {
    return array();
  }
  $diff_items = array();
  $entity = clone $context['entity'];
  $langcode = field_language($context['entity_type'], $entity, $context['field']['field_name']);
  $view_mode = empty($context['view_mode']) ? 'diff_standard' : $context['view_mode'];
  $element = field_view_field($context['entity_type'], $entity, $context['field']['field_name'], $view_mode, $langcode);
