Proposed patch at <http://codereview.appspot.com/3793046/> with comments on the 
patch going to lilypond-devel.


Tiny example, if we want this in the tracker:

\version "2.12.3"
\paper {
  % request 40mm center-to-center spacing, in 2.12 language
  between-system-space = #40
  % convert-ly replaces the line above with a 
  % request for 40-staff-space spacing, in 2.13.10 language :
  %  system-system-spacing #'basic-distance = #40
}
\score {
  \repeat unfold 3 { s1\break }
}
