It would, and I’m glad you’re encouraging me to dig up my ancient patch to do 
that, but I wasn’t thinking of making any user-visible changes in the scope of 
the work suggested in this thread.  (That could come later.)

This suggestion was motivated by recent work on cases in which both parts are 
resting.  If the desired action is to route only one of the voices to the 
shared voice, the Scheme half currently can only say “unisilence” and the 
Part_combine_iterator picks a voice.  The problem is that sometimes it doesn’t 
pick well.  It seems that the Scheme half has the information to make a better 
decision.

One way to handle this would be to add named states for other useful routing 
combinations, like dividing “unisilence” into “unisilence1” and “unisilence2”. 
I figured that might get out of hand.
