NR 1.4.1: printing-a-repeat-sign-at-the-beginning-of-a-piece.ly is obsolete since 2.18?

[Federico Bruni]

If you comment the code in this snippet the result is the same:

\version "2.18.0"

\relative c'' {
%{  \once \override Score.BreakAlignment.break-align-orders =
    #(make-vector 3 '(instrument-name
                      left-edge
                      ambitus
                      breathing-sign
                      clef
                      key-signature
                      time-signature
                      staff-bar
                      custos))
  \once \override Staff.TimeSignature.space-alist =
    #'((first-note . (fixed-space . 2.0))
       (right-edge . (extra-space . 0.5))
       ;; free up some space between time signature
       ;; and repeat bar line
       (staff-bar . (extra-space . 1)))
%}
  \bar ".|:"
  c1
  d1
  d4 e f g
}

Should  it be removed from the documentation?
