To be honest, I would be inclined to just omit the triggering entirely.
update-grub is already called in plenty of situations and we probably
don't need the complexity at this point; I certainly don't want to try
to insert dpkg triggers at this stage.

I've combined your patch with that from Didier in #773173 (though
without the extra configuration variables in the latter) and pushed a
gestalt version to git.  I should manage to upload this today.  Sorry
for the delay!
