This is the first in a series of patches that removes a bug and some glitches
from GRUB stage 1. This is against grub-0.94 (alpha)

Submitted by Wolf Lammen, ookami1<at>gmx<dot>de

I looked through the complete code of stage 1 and found some oddities.
This patch addresses one: The use of cli in the very beginning of the code.

Grub patches an address within the code directly, so when you insert new
instructions, this address moves around. The way this patch modifies stage 1
requires patching the header file as well.
