Slightly improved version below, allowing \myDisplayBarNummber to also
display bar number at beginning of line e.g. in bar 27.

\version "2.19.31"

The order of the three values is
  end of line visible,
  middle of line visible,
  beginning of line visible:
\override Score.BarNumber.break-visibility = ##(#t #t #t)
%}

myDisplayBarNummber = {
  \once\override Score.BarNumber.break-visibility = ##(#f #t #t)
}

\layout {
%  indent = 0
  ragged-last = ##t
  % Prevent all bar numbers unless overridden
  \override Score.BarNumber.break-visibility = ##(#f #f #f)
  % Allow first bar number to be displayed
  \set Score.barNumberVisibility = #all-bar-numbers-visible
}

  \bar ""

  R1*2 | \barNumberCheck #3
