Please don't; I was asleep when I typed it -- sorry.

I was hoping fsck was doing the right thing for a very low level
tool -- verify commit objects itself, without relying on the
object parser machinery which does funky things like grafts.

Apparently it doesn't -- which is mostly good.  You can safely
remove commits you wanted to discard by grafting it away like
your test did, and you can keep unrelated history you grafted to
the back of your real root commit.

For the "clone without propagating grafts" issue, I think we
need to have a way to communicate grafts across repositories.
As you say, grafts is a local policy issue, but when you start
cloning you _are_ sharing that local policy across repositories.
Futzing fsck to honor and ignore grafts at the same time sounds
like a band-aid to me.
