After some more playing I'm starting to realise that this might be a
_feature_.  Suppose you try to prove something with Sledgehammer, and it
suggests several possibilities, which you would then minimise, all
possibilities are retained in the document until you finally decide for
one proof.  However you would have to clean up yourself all those
alternatives you don't like.
