Hi Josch,

Thanks for the patch and very happy to accept that. :)

One question though, are you sure about the path not being allowed to
have a leading slash?  AFAICT, the code at least handles the link target
perfectly fine if it has a leading slash.  And I am inclined to say that
it is a bug if it does not support leading slashes in the link name either.
