* grub/asmstub.c (console_putchar) [HAVE_LIBCURSES]: If
USE_CURSES is true, emulate a new line like a ordinary terminal,
because ncurses treats it badly. If current position on y-axis
is the bottom of the screen, call scroll. Otherwise, call move
with the arguments, Y + 1 and X, where X and Y are current
position of the cursor.
