Re: [ppc patch] fix grub_ofconsole_cls on Old World

[Hollis Blanchard]

 static void
 grub_ofconsole_cls (void)
 {
  /* Clear the screen.  */
-  grub_ofconsole_writeesc ("^L");
+  grub_ofconsole_writeesc ("\e[2J");
+  grub_gotoxy (0, 0);
 }

I've verified that this patch does not break video console on my New 
World Mac, and it fixes serial console with some terminal emulators. We 
already depend on ANSI escape sequences for gotoxy(), so can we commit 
this patch now and worry about termcap later?
