Hi David,
overriding 'before-line-breaking returns the NoteColumn as X-parent of Script:
\once \override Score.Script #'before-line-breaking =
#(lambda (grob)
(let* ((nc (ly:grob-parent grob X))
(nh (ly:grob-array->list (ly:grob-object nc 'note-heads))))
(newline)(display "nc---------- ")(display nc)
(set! (ly:grob-parent grob X)
(car nh))))
log:
GNU LilyPond 2.15.39
Processing `splayed-stems-post.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
nc---------- #<Grob NoteColumn >
...
so I didn't rethink it.
The approach via 'after-line-breaking works!
Many thanks,
Harm
