block prints only the latest items

Ok, I have digged through the respective code and made experiments, and it  
would appear that bookparts and scores get their headers supplemented from  
the book (even if it is an implicit book provided by LilyPond) they appear  
in, so only books get their stuff initialized from $defaultheaders and the  
rest just starts out with an empty module.  I am reasonably convinced by  
now that this is the right way to proceed.  It is a bit of a nuisance that  
the default headers get nailed into a book at the point of time it is  
created, so that subsequent changes of header don't have an effect even if  
that book is put into a variable or something and called later.  But this  
seems more or less consistent and predictable.
