Ouch.  I thought the goal was to take

    [remote "origin"]
	fetch = $src:$dst

let the code that is used in the actual fetching to parse it into
the in-core "refspec_item", and then transform the refspec_item by

 - discarding it if the item does not result in storing in the real
   fetch

 - tweaking $dst side so that it won't touch anywhere outside
   refs/prefetch/ to avoid disturbing end-user's notion of what the
   latest state of the remote ref is.

so that the "parsed" refspec_item is passed to the fetch machinery
without ever having to be converted back to textual form.

Why do we even need to "andproduce a refspec string"?
