Yes, for me it's ready. If you are ok I can check that our new fancy
tests are still passing and merge it :)

Now, there are other locale related issues we may want to address before
the release:

* The keyboard layout issue in Grub console you reported here[1].
* The keyboard layout issue during hard drive decryption in Grub[2].

I had a quick look to the second one and using `grub-mkstandalone' seems
to be the right move but it would then require extensive testing on real
hardware.
