* terminal.c (_rl_get_screen_size) [__DJGPP__]: Determine screen
size via DJGPP-specific calls.
(_rl_init_terminal_io) [__MSDOS__]: DJGPP-specific terminal
initialization.
(_rl_backspace) [__MSDOS__]: Don't call tputs.
(ding) [__MSDOS__]: Use DJGPP-specific calls to support visible
bell.
* display.c (_rl_move_vert) [__MSDOS__]: Support cursor movement
upwards with DJGPP-specific calls.
(_rl_clear_to_eol) [__MSDOS__]: Don't call tputs.
(_rl_clear_screen) [__MSDOS__]: Support clear-screen with
DJGPP-specific calls.
(insert_some_chars) [__MSDOS__]: Don't call tputs.
