I think this is due to the kludgy extra-X-extent overrides in the
divisiones command definitions:

Joe, could you take a look at this?

Actually, I was looking at this file about a month ago, and I
noticed another problem. I'm surprised to see that I didn't report
it.

\break doesn't always work where you'd expect; this is because the
divisiones are breath marks not barlines. So doing "\finalis
\break" doesn't always work. In fact, the VaticanaVoice context
defaults to 4/4 time-signature, even though this is meaningless in
Gregorian Chant. So "\finalis \break" will only work if it happens
to land at a integer-value moment. I used this workaround:
  ancientBreak = { \bar "" \break }
Surely there's a better solution, but I don't know it.
