I've gone in and modified multi-measure-rest-engraver.cc to roughly do
what I want. I couldn't figure out how to do it with a separate
engraver (but l don't really know what I'm doing). I'd like to either
be able to get this functionality directly from a lilypond file
(without modifying the source). Any suggestions? Is modifying the
engraver and working on a good patch a better route? Thanks.
