* if a dead key sequence does not produce a special character as defined by

the dead key character map - both the dead key itself and the following
  character are being sent. 
  R5 seems to do the same, at least the resulting behaviour in the terminal
  is now identical: e.g. if you press ^ once, you see nothing, if you press ^ a
  second time, you see '^^'.
