      1  => __('Post updated.') . $view_post_link_html,
      2  => __('Custom field updated.'),
      3  => __('Custom field deleted.'),
      4  => __('Post updated.'),
      /* translators: %s: date and time of the revision */
      5  => isset($_GET['revision']) ? sprintf(__('Post restored to revision from %s.'), wp_post_revision_title((int) $_GET['revision'], false)) : false,
      6  => __('Post published.') . $view_post_link_html,
      7  => __('Post saved.'),
      /* additional messages */
  );
