phantom venom

[ I didn't keep a copy of the message which reported this
  so don't have any reference number for it. ]

     If you used '/' to look at multiple items one after another,
then looking at floor or other item represented by the same '.' as
venom could result in subsequent things being falsely categorized as
possibly venom.  The subsequent items needed to have less than two
possible descriptions, and the triggering item needed to be a plain
dot rather than the graphic dot used for floor with IBMgraphics and
DECgraphics.
