Another arpeggio collision

[Jay Anderson]

When using cross staff arpeggios a collision can occur if accidentals
cause the arpeggio to be moved to the left too much.

}

It is interesting to note that this does not occur with one staff and
two voices:

  \new Staff
  \with
  {
    \consists "Span_arpeggio_engraver"
  }
  \relative c''
  {
    \set Staff.connectArpeggios = ##t
    <<
      {r2. <ges aes c ges'>4\arpeggio |}
      \\
      {\repeat unfold 12 aes,16 <ees aes c>4\arpeggio |}
    >>
  }
