Harm, I have to prepare for a musical event tonight. I will probably be some time before I can review and understand your changes.
Please clarify whether you are using this for genuine rehearsal marks (e.g. A, B, C, ...) or whether you are expanding the abuse of RehearsalMarks to satisfy another need. I have some stale patches related to rehearsal marks that I have been hoping to return to after fixing compiler warnings. There was one that split the mark event into three classes reflecting current use: * default rehearsal mark (automatic sequence number) * specific rehearsal mark (user-provided sequence number) * ad-hoc mark (all kinds of abuse) https://codereview.appspot.com/340650043/ There was another that added a new \depart command for marks like "D.C." and "Coda" so that we wouldn't need to continue abusing rehearsal marks for those. https://codereview.appspot.com/337520043/ https://codereview.appspot.com/577180043/
