Oh, what ever was I thinking!  No need at all for all that duplicated
code...

This is all you need:

\version "2.15.36"

\relative c' {
  \override Arpeggio #'stencil = #(lambda (grob)
    (parenthesize-stencil (ly:arpeggio::print grob) 0.1 0.5 0.5 0.2))
  \override Arpeggio #'before-line-breaking = #(lambda (grob)
    (set! (ly:grob-property grob 'X-extent)
          (ly:stencil-extent (ly:grob-property grob 'stencil) X)))
  \repeat unfold 4 {
  <c g' e'>-\arpeggio
  }
  <cis dis fis gis cis dis gis>-\arpeggio
  <cis dis fis gis cis dis>-\arpeggio
  <cis dis fis gis cis>-\arpeggio
  <cis dis fis gis>-\arpeggio
}
