> Does LilyPond claim to consider skylines when choosing page-breaks ?

I don't see that it does.  And experimenting around a bit, it would be hard  
for it to claim that.  Which is somewhat weird considering that it does  
work with skylines when arranging the results of the pagebreaks (usually  
achieving even staff spacing by interleaving skylines and using the gained  
space to spread apart staves that probably were placed closer in the  
pagebreak decision), and probably did so for very long.  The difference  
2.17.1 makes is considering skylines for stencils rather than only for  
collections of stencils.

So that's definitely a different area worth investigating with regard to  
making better use of page space.  Reading the code, I was pretty sure that  
skylines figured into the pagebreak calculations.  Seeing the results, not  
so much.  So let's change the title of the summary (the problem does not  
seem to be the relation of skylines to page breaks as such).  But the basic  
problem, namely that 2.17.14 creates a serious regression for vertical  
spacing, remains.
