copies-rust: refactor the "deletion" case

We rearrange the code to single out the case where information need to be
overwritten on both side of the merge. This open the way to better dealing with
this case.

Kludge to emulate timeout(1) which is not generally available.

  press ^C again to terminate immediately (dangerous)
