Hm, then I'll define a new equal_p for probs. I'd say that two events are 
equal if all event properties are 'equal?'. This 
includes 'origin, so there will be a warning in cases like:

<<
  c8
  \mark "A"
  \mark "A"

I think this is desirable; it catches cases like
 c4 ( -. -_ -- \( (
where a user sends two slur-start-events by mistake.

My work-in-progress macro-capable parser contains a generic fix for this, 
where I added a mandatory location parameter to MY_MAKE_MUSIC. Should I try 
to backport this before 2.10?
