For pkg_add -u, we can actually be smarter and provide
old and new version to the +INSTALL/+DEINSTALL script, so that it can
itself decide to skip messages. I'm actually against just silencing the
output as we should be able to detect when new config files appear and
notify users, just to name one example.
