Minor issues when in printing links at bottom of page

There a two minor issues when printing links at the bottom of the page.

1. mailto links get the base_url in front of them
2. If your not using clean urls then the ?q= is printed twice.

I'm no programmer, but I made the following changes to the print_friendly_urls function to fix these issues.

Original code

  if ($url) {
    $urls[] = strpos($url, '://') ? $url : $base_url. '/'. url($url);
    return count($urls);
  }

New code

  if ($url) {
/*   $urls[] = strpos($url, '://') ? $url : $base_url. '/'. url($url); */
     if (strpos($url, '://') | strpos($url, 'to:')) {
        $urls[] = $url;
        } else {
        $urls[] = $base_url. '/'. $url;
        }
    return count($urls);
  }
 

Thanks
