 @c Is there a way to have a final bar ("|.") at the end of the
 @c previous line? Doesn't seem to be.
+@c It could be done by overriding
+@c the BreakAlignment property. Want a separate example?
 If you want to start a repeat at the beginning of a line and have a
 double bar at the end of the previous line, use @code{\bar}. For more
 information, see @ref{Bar lines}.
