Given that the scripts which expect the old semantic can do
hard-to-repare damage to the system, I *still* see very little
pressure to change.

This is the Perl philosophy; document only top 30% of the iceberg;
rely on users experimenting to deduce the rest.

So we are exactly where we started [you did not think that I missed
any of these arguments, did you?].  It is still one undocumented
behaviour vs the other.

And, BTW, it is not enough to code copy_overwrite().  Actually, one
should distinguish 3 possible cases: target does not exists; target
exists and is not RO, target is RO.  [Same with rename(), of course.]
