Hi David,

thanks a lot for this!!!!!!!!!!!!!!!!

Finally my question
http://lists.gnu.org/archive/html/lilypond-user/2014-03/msg00393.html
is answered:

\relative c'{
    \override NoteColumn.after-line-breaking =
    #(lambda (grob)
      (display
        (ly:grob-object grob 'conditional-elements)
        ))
    <c e g>\arpeggio
}

The 'arpeggio-property was deleted somewhere during 2.17. and I never
managed to get back the info whether a NoteColumn has an arpeggio,

Again, thanks tons!!!

Btw, the IR stating:

  conditional-elements (array of grobs)
  Internal use only.

is a joke.


Additionally the already mentioned LSR-snippet
http://lsr.di.unimi.it/LSR/Item?id=621
doesn't put out arpeggio-info any more and should be changed accordingly.


Cheers,
  Harm
