Well, that is working as intended.  The usual page-breaker will squeeze the 
staves rather than use an extra page.  The minimal-page-breaker will put as
many staves on a page as fit with their natural spacing, and never look back.

Now I realize that the documentation is missing that detail: "minimal-page-
breaking fills a page with as many systems as possible [with their natural 
spacing] before moving to the next one"  

The warning is a bit silly.  I think we want "ragged-bottom=#t" to fill pages
as much as possible within estimation error (given that there is some
estimation error) and if it underestimated the height and has to squeeze a
bit, I don't want a warning.
