Adding yet another view on Comment 5:
Bertrand quotes Gerou that we should have r4 r8 a a a beamed as r4 r8 a [a  
a] in 3/4 timing, and I consider this correct.  The crazy thing is,  
however, that I would _still_ have r4. a8 a a beamed as r4. [a8 a a] !

The reason is that in the second case, the start of the second beat  
goes "unmentioned", and that makes it a bad idea to mention its off-beat  
separately.  However, if the second beat _explicitly_ gets mentioned at its  
start, then it does not make sense to merge its off-beat into the following  
beat.

So if a rest or a beam starts at beat 2, off-beat 2+ should not get its  
beam merged into beat 3.
