between-system-spacing in the \paper block controls the spacing
(including the spring constant) between systems. For spacing within a
system, you can use the grob properties next-staff-spacing for
VerticalAxisGroup or between-staff-spacing/after-last-staff-spacing for
StaffGrouper.

The default settings are only provisional, but with this example I'm
more concerned about the wasted space that appears at the top and bottom
of each page.
