I wanted to send a new mail about this, and then forgot.

This is because of a bug in cpio.mod.  The menu code thinks grub.cfg is
present due to grub_cpio_find_file() returning here:

      if (!hd.name[0])
        {
          *ofs = 0;
          return GRUB_ERR_NONE;
        }

but I'm too clueless about tar format to figure this out.
