Thanks for raising this, but it is a known problem, see
http://code.google.com/p/lilypond/issues/detail?id=216.

Do actually need different scores to have different
spacing?
Seeing someone else raising this issue today, I thought I would now respond to 
your response.

Need?  Would I raise the issue if I didn't need it?  Almost all of my Lilypond 
usage is in support of a recorder consort.  We play mostly multi-movement works.

  *  It's very convenient to have all movements of a single work in a single 
lilypond file.

  *  We are all old.  So we have two conflicting goals:

        We would like to have all pages for a movement fit on our music stands; 
this limits us to three-page movements;

        Some of can't see so well any more, so we would like the notes to be as 
big as possible.

This means that it would be very helpful to have different movements engraved 
at different staff sizes.  We could satisfy these two goals by having some 
movements in separate lilypond files, but that is not very attractive.  

The most ridiculous aspect of this issue is that layout-set-staff-size is even 
mentioned in the documentation, where it is clearly specified how it works.  
But it's followed by an "Issue" that says, basically, don't do that because  it 
doesn't actually work.  Another ridiculous aspect is that this feature was at 
one time supported, but it was yanked because a developer never saw anyone use 
it!  How would he know?  Does he somehow look over the shoulders of all the 
Lilypond users?

Regards,
Patrick Karl
