Yes, but that's a bit more complicated than a simple pull. Anyway, Linus
seems to not be in favour of annotating commits later for adding acks,
so no need for such feature.

Thanks, I wasn't aware of this.

For some workflow - I post patches to the list, people reply with their
acks, I could just add those to notes and later fold them into the
existing commits before pushing the branch upstream. I guess it may be
just a matter of changing git format-patch to include the notes. I can
later reword he commits and drop the "Notes:" line.
