Moving to lookup_object() made me look around, but at this point the
object in question (which comes from the negotiation_tips) has been
instantiated, so it is OK.

    Side note. The big difference between lookup and parse is what
    happens when this process hasn't seen the object yet---the
    former will just return NULL instead of instantiating the
    in-core copy; for that reason, it is easier on the readers to
    use parse_object() if we know we want an in-core object *and*
    when we use it we want to see it parsed already).

This one obviously is OK ;-)  The fact we are clearing by definition
means we already do have in-core objects.

Thanks.
