Fix one of the problems From a bug report: Mjollnir is only
giving the intended feedback when it is thrown. Against ordinary
monsters the problem isn't too bad--you get a lightning message
without the preceding hit message--but against resistant ones there
is no message at all when you hit hand-to-hand. (There is a similar
bug for artifacts which add magic missile damage, but since no such
artifacts exist that isn't much of a problem. :-)
