	* term/ieee1275/ofconsole.c (grub_ofconsole_width): New variable.
	(grub_ofconsole_height): Likewise.
	(grub_ofconsole_putchar): If `grub_curr_x' exceeds console width,
	manually insert a '\n'.
	(grub_ofconsole_getwh): Set and return `grub_ofconsole_width' and
	`grub_ofconsole_height'.  Return early if these are already set.
