Url argument to drupal_feed_icon() and theme_feed_icon() has url() applied twice

I think, as a result of #715142: [beta blocker blocker] Various URLs escaped twice, since check_url() resp. filter_xss_bad_protocol() calls check_plain(), theme_more_link() now uses l(). All the usages of theme('more_link', ...) already call url() for the url argument. This causes the links generated to include the base-path twice ie http://localhost/drupal-cvs//drupal-cvs/admin/content

Should the url argument be changed to path, and all the theme('more_link, ...) calls be updated to suit and remove their url() calls? (small API change)
Or is there another option, ie rollback the theme_more_link change

current theme.inc code:

function theme_more_link($variables) {
  return '<div class="more-link">' . l(t('More'), $variables['url'], array('attributes' => array('title' => $variables['title']))) . '</div>';
}
