Not sure this is the best way: it seems sort of hackish.

maybeBreak =
\context Score
\applyContext #(lambda (c)
                (if (not (string? (ly:context-property c 'whichBar)))
                 (set! (ly:context-property c 'whichBar) "")))

{
  r8
  \repeat unfold 40 { r4 \bar "|" \maybeBreak r2 \maybeBreak r4 }
  r2.. | \bar "|."
}
