Comment 17 for bug 1178618

I had sent the patch in comment 15 to grub mailing list http://lists.gnu.org/archive/html/grub-devel/2013-09/msg00053.html. There were some comments on it and this patch is rejected.
After discussing, the maintaner wants to use the patch in comment 14.

Franz Hsieh sent one update patch to the upstream at http://lists.gnu.org/archive/html/grub-devel/2013-10/msg00070.html and I sent one ping email to upstream at http://lists.gnu.org/archive/html/grub-devel/2013-11/msg00029.html.

But still no response from the upstream.
