Hi Marc,
I am busy today, so I will look into your example later.
In short: Repeats are not taken into account right now. I thought of a factor,
that is set, when a repeat starts. But I don't know yet, how to deal with
alternatives and repeats with more than two loops. Probably the engraver might
look for barlines. Still it needs to recognize alternatives with its possible
repetitions (e.g. 1-3).
We'll crack that nut :-)
