Help on staves layout and repeat bars

[Dominique Faure]

Hi,

I wanted to get grouped staves bound together on line endings, with
repeat bars being the solely bars drawn through all the staves.
The following code address the first requirement as expected, but how
could I handle the repeat bars?

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.16.0"

notes = \relative c' {
  r1 r1
  \repeat volta 2 { r1 r1 }
  \repeat volta 2 { r1 r1 }
  r1 r1
}

\score {
  \new StaffGroup <<
    \new Staff { \notes }
    \new Staff { \notes }
  >>
  \layout {
    \override Score.SpanBar #'break-visibility = #center-invisible
    % ...also hide the repeat bar span

    ragged-right = ##t
  }
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
