The line breaker ignores page-break-permission, so it will happily return a 
line configuration where a forced page-break occurs in the middle of the 
line. The page breaker only looks at the last column in a line, so the 
page-break can be missed altogether. It wouldn't be hard to change this 
behaviour in the backend but I think it's just as easy to deal with it in the  
input stage.

Does this mean they work?

Would it break things to allow Composite_music inside a book? I think it would 
be nice to have the \pageBreak work everywhere. As for the regression tests, 
I don't see why they would require a book block.
