Hi,

try:

\version "2.16.0"

#(define span-bars-to-print '(".|" "|." ".|."))

hideSomeSpanBars =
\override Score.SpanBar #'after-line-breaking =
  #(lambda (grob)
    (let ((glyph-name (ly:grob-property grob 'glyph-name)))
    ;;(newline)(display glyph-name)
    (if (and (ly:item? grob)
             (not (member glyph-name span-bars-to-print))
             (not (equal? (ly:item-break-dir grob) LEFT)))
        (ly:grob-suicide! grob)
        #f)))

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

\score {
  \new StaffGroup <<
    \new Staff { \notes }
    \new Staff { \notes }
  >>
  \layout {
    \context {
            \Score
            \hideSomeSpanBars
    }
    ragged-right = ##t
  }
}

If you want other SpanBars to be printed, just update the list defined
as span-bars-to-print .


HTH,
