NR 4.3.6 Explicit Breaks

[Chip]

"When line-break-permission is overridden to false, Lily will insert line breaks at explicit \break commands and nowhere else."

I can't get this to work as quoted from the NR. Lily still breaks lines where it wants to.

My problem is this: I have many short snippets of music - horn (trumpet, trombone, sax) riffs. Some are as short as 2 measures, others might be as many as 20 measures or so. When the .pdf is created the staffs are of various lengths, and have huge space between them, sometimes just 3 staves are spread out over the full height of the page. Very weird looking. I've been messing around with the various ragged-... settings trying to get the staffs all the same length with the last staff to end at it natural length. And all printed in a nice looking block from the top of the page and ending, in my cases, in the middle of the page at the lowest. I just haven't found the magic combination to get this to work. Pasted below is the .ly file I am working on. Can someone help me?
