Comment #5 on issue 442 by joeneeman: Enhancement: RemoveEmptyStaffContext  
shouldn't reduce PianoStaff to one staff

The patch linked below adds this functionality with a context property. You  
have to name the staves that you want to keep alive together, so there is  
no ambiguity coming from nesting. In Kieren's original example, you would  
need to add
\with { keepAliveWith = #'("three")) }
to staff two and
\with { keepAliveWith = #'("two")) }
to staff three.
