Thanks, that did it!

Still, there is one minor annoyance:

Note there is an additional `/' when the link has a leading `/' (but 
not just `/'), i.e., `//' => `///', `/.' => `//.', `/tmp' => `//tmp', 
`//tmp' => `///tmp'.  For FreeBSD CD-ROMs, `stand -> /rescue' becomes 
`stand -> //rescue', etc.

Can you take a look at it, too?

Thanks a lot!
