segno on barline in 2.0.0

[Paul Scott]

I came up with this example trying to get a segno on a barline.  I tried 
an old and a new way to do this.  Can someone tell what's going on 
and/or how to get a segno on a barline in 2.0.0?

TIA,

Paul Scott

#(define segno '(music "scripts-segno"))

\score {

                \notes {
                    \time 3/4
                    R4*3*8 \mark \segno
                    R4*3*2 \mark #`,segno
                    d'2\pp\fermata r4 \bar "||"
