Subject: allow frontends to override releaseinfo change behaviour
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Having messages being printed on the error stack and confirm them by
commandline flags is an okayish first step, but some frontends will
probably want to have a more interactive feeling here with a proper
question the user can just press yes/no for as for some frontends a
commandline flag makes no sense…
