once per Staff, not once per Voice

As far as I can see, the Mozart horn stuff does not use instruments, so  
whatever the reason for the problem may be, it would not be related to this  
change.  We probably need to watch out for similar occurences.

The changed regtest in the screenshot, however, would seem serious.
