Just apply on top of master.

git clone git://git.savannah.gnu.org/grub.git
cd grub
git am e-mail-with-patch

I do not know what other patches Debian has, so using upstream directly
may lose Debian specific changes. Also you would need to build using
correct configure options.

I would suggest to build it for different prefix, like

./autogen.sh
./configure --prefix=/usr/local/grub-test
make
make install

then run /usr/local/grub-test/sbin/grub-mkconfig and examine generated
configuration.

I myself do not use Debian, sorry.
