Thanks, this works well for multimeasure rests. But I would also like 
the same mark to work for another staff that has music in it. With these 
overrides, that looks weird: the markup is stretched over an empty 
space, the music starts after it.

Is there some trickery to find out whether the mark has rests following it?
Or is there some trickery to selectively disable these overrides by 
hand, e.g. when there are notes?
Ultimately, I would like to be able to specify where in time the markup 
ends -- that would give lots of control.
