I've committed the patch (slightly polished, as said). Let's see how it
goes on. I cannot test anything myself, I don't use Windows machines.

Unfortunately, not. In tramp-*-handle-expand-file-name, expand-file-name
is called for the local part of a remote file name in order to handle
"./" and "../". On Windows, this prefixes the result with the volume
letter, which must be removed afterwards.
