Do not perform this copy operation, IF the .orig file does already exist
(from the earlier "make patch" step).

I'd also use "cp -p" to preserve the original modification time, which
will be included in the patch ...

Else, your change will be against a patched file, without the patch that
lead to this state being conserved.
