I definitely would like to be fancy. I think I'll not only check if
the branch has been rebased, but also test the rebased branch out to
make sure the problem is still there. I've been doing this check for
the build bisects. When doing so, it no longer matters how the rebased
branch differs from the original branch in source code level. For
example, even the simple rebase to a new RC base might make a problem
