Tell you what: I'm still days away from getting my code finished (which is  
pretty much a rewrite of the whole function).  The current code is a heap  
of assumptions and heuristics.  Making Valentin's current bounty case (and  
a few more) work out better is reasonably simple in contrast, and that is  
what this issue and its bounty is about, and Valentin has a score to get  
published.  You can't make this do the right thing in cases involving  
harmonics in non-trivial ways, and it won't ever work right with "string  
chords" where the individual notes have different durations, which is one  
of the reasons I have not further worked on patches in that area (I am  
actually surprised that there does not seem to be an issue for those; I  
remember Werner requesting them in the context of the Bach solo violin  
works).

So this needs to be done right, and in the mean time I have a conference  
talk about LilyPond coming up for which not one slide has been written yet  
and where I leave on Friday.  I have to put this on hold till at least the  
next week.  So go ahead with the quick fix if you want (and there is a need  
for it, anyway, and a bounty).  It does not really interfere with my work  
on this function, and that will have to carry at least into next week.
