I agree our use of cp -i </dev/null is a little too fancy not to be
explained in the docs, so I have done so with the attached, applied

As far as "...", those are used to show only the important changes in
the string, which I think is the right approach, but I did change the
line so the dots are not right up against slashes:

archive_command = 'test ! -f ... %f &amp;&amp; cp %p ... %f'
