-The @code{Volta_engraver} by default resides in the Score context, and
-brackets for the repeat are thus normally only printed over the
-topmost staff. This can be adjusted by adding @code{Volta_engraver}

@c Is there a way to have a final bar ("|.") at the end of the

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
+double bar at the end of the previous line, use @code{\bar}. For more
