Reviving this old thread. I was trying to do this today and found the
same frustration. It looks like it requires a simple change to the
code:

Is this an appropriate approach? Ideally it'd be nice to give it a
list of things that cause beams to end (e.g. breathing sign, manual
beam, bar line, etc.).
