Comment #8 on issue 984 by address@hidden: Noteheads don't merge when one of  
the voices contains a second
http://code.google.com/p/lilypond/issues/detail?id=984

In previous comment, "second example" actually refers to the group in the  
second measure (which is quite far from being the second example).  This is  
an interesting corner case.  Since I am still tempted to do an algorithmic  
patch replacing the stream of exceptions in the current implementation, it  
would be nice to get a quotation from a reference.  If this figure were  
merged, one would basically have one visual stem running from top to  
bottom, with flags at top and bottom.  The notehead configuration can be  
considered compatible, but would that kind of straight stem be acceptable?
