And that commit was reverted a week later in grub commit
faf4a65e1e1ce1d822d251c1e4b53d96ec7faec5 ("Revert grub-file usage in
grub-mkconfig."), see
http://git.savannah.gnu.org/cgit/grub.git/commit/util/grub.d/20_linux_xen.in?id=faf4a65e1e1ce1d822d251c1e4b53d96ec7faec5 .

That commit has no explanation (other than its one line summary). So
we're left guessing why this was done. Luckily, it doesn't matter here,
because the test for CONFIG_XEN_PRIVILEGED_GUEST is superfluous.

Anyhow, I hope to submit a second version of this patch later this day.
