Hi Harm,

cross-staff-chords---beaming-problems-workaround.txt:cross-staff-chords---beaming-problems-workaround.ly:39:11:
warning: ignoring too many clashing note columns
--As expected! Same warnings as in 12.2.3

I realize that it's not necessary for an update that warnings be fixed, so feel free to ignore this :)

Overriding #'ignore-collision gets rid of the warnings (the relevant line seems to have been lost between the exchange that prompted this snippet and its final form--see http://lists.gnu.org/archive/html/lilypond-user/2011-06/msg00124.html):

 \new PianoStaff <<

  \new Staff = up

    \relative c' {

      <<

        { r4

          \override Stem #'cross-staff = ##t

          \override Stem #'length = #19 % this is in half-spaces,

              % so it makes stems 9.5 staffspaces long

          \override Stem #'Y-offset = #-6 % stems are normally lengthened

              % upwards, so here we must lower the stem by the amount

              % equal to the lengthening - in this case (19 - 7) / 2

              % (7 is default stem length)

          e e e }

        { s4

          \change Staff = "bottom"

          \override NoteColumn #'ignore-collision = ##t

          c, c c

        }

      >>

    }

  \new Staff = bottom

    \relative c' {

      \clef bass

      \voiceOne

      g8 a g a g a g a

    }
