The simplest way to ask LilyPond to stretch big orchestral systems a little less, was to 
tell her to consider the space between systems, and the space at the bottom of the page, 
to be *very* stretchable.  These adjustments are in "paper_adjustments.ily" 
attached.

I worried that this adjustment would make Nick's problem even worse, *but* on 
my parts the extra space at the bottom remains uniform, 1 to 1.5 staff spaces, 
even though the staves are quite uneven due to page-turn considerations.

We should get the bottom staves to be perfectly even across pages, if we sets 
the bottom stretchability to zero:
\paper { last-bottom-spacing = #'(
  (space . 1) (padding . 1) (minimum-distance . 0) (stretchability . 0)
  )}
I set the full list of parameters above, even though I changed only one of 
them, to work-around recently-reported bug 1338.


My first draft of adjustments is attached, and the toy score below shows how I 
use them.  The files are mostly comment, with just a few overrides.  While 
experimenting, I found it helpful to prevent the number of pages from changing, 
using \paper{page-count=#5}


Jan and choral folk,  maybe a little more #'non-affinity-spacing is needed to 
keep the Lyrics from being confused with the next staff?   You know that I have 
no experience with vocal music, but these files make Jan's setting of the 
Messiah look good to my eyes.

I will be quiet for a couple days over the weekend, but will not forget this.
