Source code links with add_language_extension() are incorrect

[eruber]

With the following in config.ld:
add_language_extension('ttslua','lua')
prettify_files=true

The output source is correctly generated as in:
output/source/vector.ttslua.html

However, the source code links generated in the output/modules/vector.html module file is to:
output/source/vector.lua.html
which is incorrect.

Perhaps I am missing a config setting?

I managed to fix this in ldoc/html.lua in the function ldoc.source_ref() which I changed to this:
function ldoc.source_ref (fun)
local path
local ext
path, ext = tools.split_dotted_name(fun.module.file.filename)
local modname = fun.module.name
local pack,name = tools.split_dotted_name(modname)
if not pack then
name = modname
end
-- return (ldoc.single and "" or "../").."source/"..name..'.lua.html#'..fun.lineno
return (ldoc.single and "" or "../").."source/"..name..'.'..ext..'.html#'..fun.lineno
end

I sent a pull request for my fix.
