Re: RemoveEmptyRythmicStaffContext

[Mats Bengtsson]

As far as I can see, it only happens if you don't have any other
stave on that line of the score, so the full score line has to be removed.
Since this should never happen in any real piece of music (possibly with
the exception of "4.33" by Cage), it makes sense that LilyPond gets
confused. Still I agree that the printout could be more to the point.
Actually, if you use an ordinary Staff (with \RemoveEmptyStaffContext),
then you will still get the first "Programming error" message:
programming error: system with empty extent
even though it actually is a user "error".
