concerning staff-affinities
http://code.google.com/p/lilypond/issues/detail?id=1555

This is leaping out at me as another issue that requires a documentation  
solution. I don't really understand the contexts and how 2.13 has changed  
them, but, as ever, it's got to be possible to take a file that compiled  
clean in 2.12, read the docs, and then make te same file with a few tweaks  
compile clean in 2.14.  Can anyone document how this need to set affinities  
in 2.13 works?
