Configuration form variant links

When adding form col variants with the alter hook the links don't show because they are put on #value rather than #markup.

The correct syntax for the form api should be nodeformcols.admin.inc:127

    $form['variant'] = array(
      '#type' => 'item',
      '#title' => t('Select a form variant'),
      '#markup' => theme('links', array('links' => $variant_links)),
    );
