optionall disable redisplay in command editor clear screen function
* oct-rl-edit.c (octave_rl_clear_screen): Likewise. If skip_redisplay
is true, override rl_redisplay_function. Otherwise, just call
rl_clear_screen.
* cmd-edit.h, cmd-edit.cc (command_editor::clear_screen,
command_editor::do_clear_screen, gnu_readline::do_clear_screen):
New arg, skip_redisplay.
* sysdep.cc (Fclc): Pass true to command_editor::clear_screen.
