Right, we currently offer the ability to navigate to a default _submenu_
but I think that it's bad UI to relegate the most oft-used entry to a
submenu entry instead of the top-level entry. I would like to be able to
specify the top-level entry, that is the first entry in the first menu.

My patch description says:

        Introduce the GRUB_TOP_LEVEL, GRUB_TOP_LEVEL_XEN and
        GRUB_TOP_LEVEL_OS_PROBER variables to allow users to specify the
        top-level entry.

and I'm not quite sure how to make it more clear other than, perhaps,
explaining what the top-level entry means.
