Thanks.  I'm going to simplify this a fair bit after consultation with
the kernel folks, and based on general shell style; the tests can be
done much more compactly, we don't need to emit noise on stderr when the
hook script isn't doing anything, and we should definitely not be
hardcoding the path to update-grub.  Also, Ben Hutchings advised me that
the comment about which packages set DEB_MAINT_PARAMS is incorrect, so
I'll leave it out rather than providing incorrect information.

I can take it from here, though.

There's a draft policy for this now, which I shall follow.
