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).
