\betweenLilyPondSystem : strange behaviour

[Jean-Charles]

Hi Graham!

Sorry to bother you again with it, but I really get messed up:

I tried to play around with the test.lytex Laura Conrad sent with 
http://lists.gnu.org/archive/html/lilypond-user/2007-06/msg00424.html to 
figure out what was so strange with me, since her spacing is fine but 
not mine.

It seems to me that as long as there is no "header" section in the 
lilypond environment, the first two systems get sticked together.
Uncommenting the header line makes it work correctly.


======== sticky.lytex =========
\documentclass[a4paper,12pt]{book}
\usepackage[frenchb]{babel}
\newcommand{\betweenLilyPondSystem}[1]{\linebreak \vspace{36pt}}
\begin{document}
\begin{lilypond}
%  \header {title = " "}
  {c'1\( e'( c'~ \break c' d) e f \break c' d) e f\)}
\end{lilypond}
\end{document}
=================================


Is this my fault or not ?

TIA
Jean-Charles
