  * Tidy up the hat-detect user interface.
      * command T now means 'start hat-trail'
      * command to `trust' must be spelled in full
      * command to `suspect' must be spelled in full
      * new command E means 'start hat-explore'
      * prompt is now just "? " rather than "(Y/?Y/?N/N): "
