Argh, c/p-fail.
This is the code:
{
  \override DynamicText.X-offset =
    #(lambda (grob) (ly:grob-set-property! grob 'stencil '()))
  c'1
    -\tweak before-line-breaking
      #(lambda (grob)
        (ly:grob-set-property! grob 'stencil
          (grob-interpret-markup grob "very long dynamic")))
    -#(make-music 'AbsoluteDynamicEvent)
}

Cheers,
