I think so. I have not thought things through to say if replacing a
"full path in the current drive" with system_path() is a sensible
thing to do in the first place, but I am getting the impression from

In any case, the helper is about expanding ~/foo and ~who/foo to
absolute paths, without touching other paths, so it is a wrong
function to implement it in, even if the motivation were sensible.
