relative link to arbitrary file in html conversions

[GoogleCodeExporter]

I like vim wiki for taking notes and linking files. But I also like the easy 
way to convert the wiki into static HTML that I can easily publish.
I used it for many years but decided to update the old version I had for the 
last one. I managed to update all my syntax etc.

However I could not figure how to link an arbitrary file from a static 
directory as I was doing with previously.

I tried many 'schemes':
   [[file:URL]] does not add the server address into the url 
   [[local:URL]] add my local disk path
   {{URL}} consider only images
   [[URL]] adds a .html at the end
   [[URL/]] adds a / at the end but almost do what I need.

in other words none of the schemes I tried converted the link as follow:
[[<scheme>:URL]] into http://BASE/URL (with the appropriate html syntax)

I managed to hack something, but I'd rather the proper way to do this (if any). 

Below is the patch corresponding to what I did to define a 'remote:' which may 
not be the best name:
