At the present time, there are no user-settable rules for determining
beamlet direction.

I believe that the outcome in measure 2 should be always preferred.

I've been trying to improve the algorithm for doing this, but it's not yet
perfect.

Unfortunately, due to some health issues in my family I have very little
LilyPond time right now.

Please post this as a bug; I'll try to fix it in the near future.

Thanks,
