   1 Xterm behaves oddly with CSI 3 J.  This function is supposed to clear the
   2 saved lines in history.  Xterm does this, but a small number of lines of
   3 history are not cleared.  The number seems to vary with how high the window is
   4 and how much output has recently been saved.  There is no reason to simulate
   5 this behavior, so the expected outputs are as if the entire history was
   6 erased.
