discovering divine gifts

     <Someone> says he reported this five years ago, but I don't think I ever
saw it.  Receiving an artifact as the result of #offer would add it into
the discoveries even if the hero was blind and never saw it.  It either
needed to have the dknown bit set, as if it had been seen, or else should
not be added to the list.  I've opted for the latter.
