drupal_add_js - always prepends $base_url

I wanted to add some javascript to a page from another website, so I put in:

drupal_add_js("http://www.somesite.com/stuff/mycode.js", 'module')

but the function added $base_url to the front, which broke the url.

I made a simple change to drupal_get_js in common.inc that seems to solve the problem:

    switch ($type) {
      case 'setting':
        $output .= '<script type="text/javascript">Drupal.extend({ settings: '. drupal_to_js(call_user_func_array('array_merge_recursive', $data)) ." });</script>\n";
        break;
      case 'inline':
        foreach ($data as $info) {
          $output .= '<script type="text/javascript"'. ($info['defer'] ? ' defer="defer"' : '') .'>'. $info['code'] ."</script>\n";
        }
        break;
//mitch - need something that doesn't make a relative path!
      case 'remote':
        foreach ($data as $path => $info) {
          $output .= '<script type="text/javascript"'. ($info['defer'] ? ' defer="defer"' : '') .' src="'. check_url($path) . ($info['cache'] ? '' : '?'. time()) ."\"></script>\n";
        }
        break;
//mitch
      default:
        foreach ($data as $path => $info) {
          $output .= '<script type="text/javascript"'. ($info['defer'] ? ' defer="defer"' : '') .' src="'. check_url(base_path() . $path) . ($info['cache'] ? '' : '?'. time()) ."\"></script>\n";
        }
    }

What do you think?

Is there a better way to solve this?

Thanks,
