Printing bar numbers for broken measures

By default, a bar number of a broken measure is not repeated at the beginning of the new line. Use first-bar-number-invisible-save-broken-bars for barNumberVisibility to get a parenthesized BarNumber there.

\version "2.24"

\layout {
  \context {
    \Score
    barNumberVisibility = #first-bar-number-invisible-save-broken-bars
    \override BarNumber.break-visibility = ##(#f #t #t)
  }
}

\relative c' {
  c1 | d | e | f2 \break
  fis2 | g1 | e2 \break
  <>^"reenabled default"
  % back to default -
  % \unset Score.barNumberVisibility would do so as well
  \set Score.barNumberVisibility = 
    #first-bar-number-invisible-and-no-parenthesized-bar-numbers
  es2 | d1 | c 
}
