+   This is a barline that is spanned across other bar lines.  This is
+   the implementation of the long barlines that occur in orchestral
+   score and other multi-staff music.
+
+   TODO: Is this usable for other stuff besides barlines? We only have
+   to span a Score_element.  Perhaps this can be used for large time
+   sigs?
