Not taking into accoung $base_url

My drupal site is under a sub folder (i.e.: www.blablabla.com/subfolder/)

When entering the url, I would expect the "/subfolder" to be added "magically", but it is not. And the documentation shows "internal link". Theses two points are inconsistent:
- either it is a internal link, and "/subfolder" should be added magically (you can use the global $base_url variable that contains that info)
- either it is not an internal link, and the label should be adapted accordingly

When specifying "/subfolder/1" as destination, it works as expected.

Thanks you for your great module, a big time saver !!!
