Comment #9 on issue 2462 by [email protected]: unnecessarily wide spacing
caused by Lyrics
http://code.google.com/p/lilypond/issues/detail?id=2462
The guilty code seems to be spring.cc:103 inside merge()
avg_distance = max (min_distance + 0.3, avg_distance);
avg_distance is then used as the ideal spacing between columns.
An interesting experiment to see how the regtests look after removing that
line.
The discussion of the patch to issue 1779 shows a previous attempt to move
the 0.3 somewhere more appropriate; it should probably be a property of
spaccing-spanner.
