  Modify directory name reading to be interrupted with operator or pound escape.
  
  In the case of accidentally entering the wrong first three letters for the
  reading, users could be very frustrated if the name listing is very long. This
  allows interrupting the reading by pressing 0 or #. 0 will attempt to execute
  a configured operator (o) extension and # will exit and proceed in the
  dialplan.
