The point is to see where changes are happening, and to be able to cherry pick in a migration toward the latest [but being able to spot the deltas from the prior version], which, as I understood it, was your goal I did not suggest applying that resulting diff, as a patch without review, but rather as a means to get visibility as to what changes were being 'upstreamed' -- Russ herrold
