full repeat bracket for 2nd ending

[Richard Wattenbarger]

I'm typesetting a score in which I have first and second endings. I would like the bracket for the second ending to conclude with a vertical line, but I haven't quite figured out how to make this happen.  I've tried various tweaks involving VoltaBracket but to no avail. 

Suggestions?

Here's a simplified example

notes = 
\relative c' {
  \clef treble {
    \repeat volta 2 {
      c1
    }
    \alternative {
      {d}
      {e} % after this ending, I'd like the bracket to be end with a vertical line
    }   
    g
  }
}

\score {
  \notes 
}
