+	* 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.
