H2162 - topten handling of long names

<Someone> reported that being killed by a monster with a long name
can result in nethack going into an infinte loop printing spaces.  Handle
this by detecting attempts to wrap the topten output on a word that is too
long and just inserting breaks in the middle of the word in this case.
