URL aliases are now treated correctly

Contrary to what's said in the comment (compare with the internal and path alias), the internal path appears twice.

          // Compare with the internal and path alias (if any).
          $page_match = preg_match($regexp, $real_path);
          if ($path != $real_path) {
            $page_match = $page_match || preg_match($regexp, $real_path);
          }

Here is the correct code:

          // Compare with the internal and path alias (if any).
          $page_match = preg_match($regexp, $alias);
          if ($path != $real_path) {
            $page_match = $page_match || preg_match($regexp, $real_path);
          }
