New issue 1991 by address@hidden: Improve vertical positioning  
of 'loose' lines: Lyrics, Dynamics,
http://code.google.com/p/lilypond/issues/detail?id=1991

Notes and articulations sometimes project through lines of Lyrics or  
Dynamics, and these projections might determine the spacing between Staves  
with the Lyrics in  between.
  \new PianoStaff <<
    \new Staff {g'2 e}
    \new Dynamics {s2\p s2} % nominally centered
    \new Staff {\clef bass g2 g'} >>
The current spacing algorithm puts a Spring between the Staff and Dynamics,  
and another between Dynamics and the second Staff.  In order to spread the  
staves in this example, the second Spring has its internal "rod" lengthened  
so that the sum of minimum Spring lengths will hold the Staves far enough  
apart.

A more sophisticated method, similar to that in notspacing, might be  
worthwhile: using an additional rod from Staff to Staff to spread them for  
the g' and e, so the Dynamics can center itself on its own Springs.

Resolution might help to resolve issue 1669, issue 1127
