three questions in one

[胡海鹏 - Hu Haipeng]

Hello,
  Here're three problems:
  1. The recent devel versions can't work properly. Under XP, if I press enter on the file attaached (and all other files), both 2.13.11 and 12 gives out abort message, saying whatever RAM can't be "read".
  2. When running 2.13.12, the warning before its abort tells me that skip_event_swallow_translator is changed. But when I look up it in IR, I can't get a clue. Also, when I look up the LM, the template only gives \new Dynamics without any tweaking. Does it mean this context has been added to LP's built-in functionality? I need to know it because there're some contexts I created as this kind, e.g., one for tempo and rehearsal marks, and one for functional chord indication markups.
  3. \RemoveEmptyRhythmicStaffContext seems not available. I still use 2.13.7. Was it added after it?

Regards
Haipeng
