function signature_forum_comment_view($comment, $view_mode, $langcode) {
  if (variable_get('user_signatures') && !empty($comment->uid) && !empty($comment->signature) && !empty($comment->signature_format)) {

    // Add signature_forum to the render array.
    if (!isset($comment->signature_forum_status) || $comment->signature_forum_status) {
      $comment->content['signature_forum'] = array(
        '#signature' => check_markup($comment->signature, $comment->signature_format, '', TRUE),
        '#theme' => 'user_signature',
        '#pre_render' => array(
          'signature_forum_pre_render_user_signature',
        ),
        '#user' => user_load($comment->uid),
      );
      $body = field_get_items('comment', $comment, 'comment_body', $langcode);
      if ($body) {

        // Some body fields appear not to have a 'safe_value'.
        if (!empty($body[0]['safe_value'])) {
          $content = $body[0]['safe_value'];
        }
        else {
          $content = $body[0]['value'];
        }
        $comment->content['signature_forum']['#content_length'] = drupal_strlen(strip_tags($content));
      }
      else {
        $comment->content['signature_forum']['#content_length'] = 0;
      }
      $comment->content['signature_forum']['#comment'] = $comment;
    }

    // Unset the core signature.
    unset($comment->signature);
    unset($comment->signature_format);
  }
  return $comment;
