By the way, is the feature itself something we can test easily?  I
think I saw the "we must interact with --root sensibly" test, but
the actual feature not being tested include

 - rebase.forkpoint set to false and then to true; does it use the
   fork-point feature (your patch as-is would have failed this test);

 - rebase.forkpoint set to false and command line says --fork-point;

 - rebase.forkpoint set to true and command line says --no-fork-point;

I offhand do not know if it is easy to observe it the fork-point
feature gets triggered, but it seems that the difference in
behaviour is big enough for you to care, so I am hoping you may
think of a way.

Thanks.
