  15   12  DESCRIPTION
  16      -       The  free_rtn structure is referenced by the  datab structure. When
  17      -       freeb(9F) is called to free the message, the driver's message-freeing
  18      -       routine (referenced through the  free_rtn structure) is called, with
  19      -       arguments, to free the data buffer.
       13 +     The free_rtn structure is referenced by the datab structure.  When
       14 +     freeb(9F) is called to free the message, the driver's message-freeing
       15 +     routine (referenced through the free_rtn structure) is called, with
       16 +     arguments, to free the data buffer.
