    Revert "support REP (repeat) escape sequence"

    This reverts commit e8392b282c2eaa28725241a9612804fb55113da4.

    There is currently a bug in older ncurses versions (like on OpenBSD) where a
    fix for a bug with REP is not backported yet. Most likely in tty/tty_update.c:

    Noticed while using lynx (which uses ncurses/curses).
    To reproduce using lynx: echo "Z0000000" | lynx -stdin

    or using the program:

    int
    main(void)
    {
    	WINDOW *win;
    	win = initscr();

    	printw("Z0000000");

    	refresh();

    	sleep(5);

    	return 0;
    }

    This prints "ZZZZZZZ" (incorrectly).
