Oops. Of course I know that. But didn't I write something like "forest 
for the trees"?

No, I wasn't aware of this.
Your solution is definitely better than mine. But I even like Janek's 
version more for this.

Well, I dont merge the rests but skip them in one voice.
I'll look into this.

OK, this makes my embarrassment over 1) smaller ;-)

@all who commented on the coding:
I will collect this sort of feedback and will deal with it when I've 
come home from vacation.
Some of the suggestions will replace my coding, some I will comment in 
the text and for some I will reference to the respective email comments 
(pointing even more to the community aspect).
