I do not think so.

Extending the example (sorry for doing the same topic on two
separate threads) I just gave Jeff on "fix based on v0.99",
after finding that the fix is based on v0.99, finding another
commit that immediately followed the v0.99 commit on my master
branch does not help finding out that I very recently merged the
fix in at all.  I think we cannot get away without honestly
doing the first descendant, which is unfortunately a lot more
expensive.
