Lines per page

[Helge Kruse]

Hello,

I have a score adapted for harp trio. I want to put it on four pages to 
reduce the page turns. The slow part starting at last measure on page 2 
is also convevient for page turn. On pages 1,2 and for Lilypond has put 
four lines on the page. But on page 3 there is a lot of space while the 
page 4 is very condensed. Why doesn't Lilypond equally put 4 lines on 
each page and how can I circumvent this?

This happen only in the complete score. Reducing it to a minimal example 
removes the problem. Since the score may to too large to put it to the 
list, I dropped it here:
