Incorrectly formed link

The update to 1.4 has introduced a bug...

If you are in the root level of the website, links work correctly. Example:

http://www.example.com/finish/my-finish

If you move down one level, this stops working, as the function creating the link does not work as per the l() command. If you are on the "finish" page, and a link is present with the link text is set to "finish/my-finish", the link appears as:

http://www.example.com/finish/finish/my-finish

This causes a lot of recursion which shouldn't exist, and problems with broken links and search engine submission.

A quick way around this is to insert a '/' into the link code, but this only works if the website is in the root of the domain, otherwise it will break...
