function form_process_button($element, &$form_state) {
    // We normally want to add drupal.form-single-submit so that the double submit
    // protection can be added to the site, however, with the addition of
    // javascript_always_use_jquery, this would make most pages with a login
    // block or a search form have jquery always added, changing what people who
    // set the javascript_always_use_jquery variable to FALSE would have expected.
