Record open questions and reasons in issues

A question to the user that is still open at the end of a session goes
on the issue as a comment, with the options and a recommendation, and
the answer follows as a comment. Otherwise the question is lost when the
session ends, and a new agent cannot see it. Each decision comment gives
its reason, so that a later agent does not undo the decision.
