automatic page breaks changed for 2.9.8?

[Paul Scott]

A part produced with:

\book {
   \score { }
   \score { }
}

Using 2.9.8 seems to force a page break at the end of a movement 
(\score) whether there is room for part of the next movement or not.  
That is unless there is room for the next whole movement.  This is very 
neat but if there is not a way for a choice I think there should be.  
2.8.4 does the more normal page breaking.

I can produce my example if necessary.
