Well, broken text isn't that hard:

\version "2.19.32"

foo =
\override Staff.OttavaBracket.after-line-breaking =
  #(lambda (grob)
     (let* ((orig (ly:grob-original grob))
            (siblings (if (ly:grob? orig)
                          (ly:spanner-broken-into orig)
                          '())))
      (if (> (length siblings) 1)
          (for-each
            (lambda (sib) (ly:grob-set-property! sib 'text ""))
            (cdr siblings)))))

mus =
\relative a {
  \foo
  \ottava #-2
  a2 b
  \break
  a b
  %\ottava #0
}

\new StaffGroup
<<
  \new Staff \mus
  \new Staff \repeat unfold 2 R1
>>
