I think in the longer term "--ignore-if-in-upstream" that is known only to
format-patch, which is the true source the intelligence of rebase you
observed comes from, should be factored out into a helper function that
can be used to filter output from get_revision() in other commands, or
perhaps get_revision() itself might want to learn it.

I say "or perhaps might" above, because I do not think the general
revision traversal machinery used by the log family (which cherry-pick's
multi-pick option relies on) has enough information to decide what the
caller means by "upstream" at the point setup_revisions() is called.
