bones fix

From the newsgroup:  leash found inside a bones level shop was flagged
as "in use".  3.4.0 had a fix for that which works for most cases, but not
when the shopkeeper has taken the dead character's inventory just before
saving the bones file.

     This also adds an entry to the branch copy of fixes34.2 to synchronize
it with the trunk copy.
