-Bar numbers can be typeset at regular intervals instead of just at
-the beginning of every line. To do this the default behavior
-must be overridden to permit bar numbers to be printed at places
-other than the start of a line. This is controlled by the
-@code{break-visibility} property of @code{BarNumber}. This takes
-three values which may be set to @code{#t} or @code{#f} to specify
-whether the corresponding bar number is visible or not. The order
-of the three values is @code{end of line visible}, @code{middle of
-line visible}, @code{beginning of line visible}. In the following
-example bar numbers are printed at all possible places:
-
-@lilypond[verbatim,quote,relative=1]
-\override Score.BarNumber.break-visibility = ##(#t #t #t)
-\set Score.currentBarNumber = #11
-% Permit first bar number to be printed
-\bar ""
-c1 | c | c | c
-\break
-c1 | c | c | c
