Here is the solution I came up with.  Replace the definition of
octave_rl_clear_screen in liboctave/oct-rl-edit.c with the following
code.

// It would be much simpler if we could just call _rl_clear_screen to
// only clear the screen, but it is not a public function, and on some
// systems, it is not exported from shared library versions of
// readline, so we can't use it.
//
// Instead, temporarily redefine the redisplay function to do nothing.
//
// XXX FIXME XXX -- It would be safer to do this when protected from
// interrupts...

static void
no_redisplay (void)
{
}

void
octave_rl_clear_screen (void)
{
  int ignore1 = 0;
  int ignore2 = 0;

  rl_voidfunc_t *saved_redisplay_function = rl_redisplay_function;
  rl_redisplay_function = no_redisplay;

  rl_clear_screen (ignore1, ignore2);

  rl_redisplay_function = saved_redisplay_function;
}
