FYI, for two voices per staff, recent (2.19.16) changes to the part combiner 
are supposed to merge both rests and multi-measure rests when appropriate.  Of 
course, you must be willing to accept the part combiner's decisions about solo 
passages etc. or use those tedious \partcombineX commands.

It would be nice if concurrent simultaneous rests could be merged without 
requiring the part combiner.  Then we could simplify the part combiner.  (You 
might be a programmer if you enjoy undoing hours worth of work as much as doing 
it in the first place.)
