How to repair volta bracket ending?

[Dominic Neumann]

Hello,

I have a song with three different repeat endings and special volta bracket 
text. Everything works fine except the middle volta bracket has no vertical 
line at the right end. Can you please help me with this?

Thanks
Dominic




\version "2.14.2" 

voltaI = \markup { 1. 3. 5. }
voltaII = \markup { 2. 4. }
voltaIII = \markup { 6. \text \italic { "Fine" } }

\score {
    \new Staff <<
        \relative c'' {
            g1 |
            \repeat volta 3 {
                a1 | b1 |
            }
            \set Score.repeatCommands = #(list (list 'volta voltaI))
            c1 |
            \set Score.repeatCommands = #(list (list 'volta voltaII) 
'end-repeat)
            d1 |
            \set Score.repeatCommands = #(list (list 'volta voltaIII) 'volta 
#f) 
            \bar "||"
            e1 |
            \set Score.repeatCommands = #'((volta #f))
            \bar "|."
        }
