Fwd: \bar "" as discretionary break point without affecting spacing

[Daniel Tobias Johansen Langhoff]

Thank you!

I ended up doing this because I want the breath marks to be a bit off
the right edge.

%%%%
\version "2.20.0"

lineEnd = {
  \once \override BreathingSign.space-alist.staff-bar = #'(minimum-space . 0)
  \once \override BreathingSign.space-alist.right-edge = #'(extra-space . 1.0)
  \breathe \bar ""
}

\score {
  \relative a' {
    \override Score.BarLine.break-visibility = #end-of-line-invisible
    \omit Score.TimeSignature
    \cadenzaOn
    \repeat unfold 5 {
      \repeat unfold 8 { a4 } \lineEnd
    }
    \repeat unfold 8 { a4 }
    \revert Score.BarLine.break-visibility
    \bar "|."
  }
}
%%%%
