repeats in parallel mode?

[William Bajzek]

I just read about the \parallelMusic function and was trying it out. First of 
all, I'd like to say that I think it's great because it is a very convenient 
way to lay out multi-voice music. The problem I've run into can be seen in the 
following; I expect it to emit two measures but it emits four instead. 
Hopefully my intent is clear enough; what's the right way to do this?


\version "2.12.3"

\parallelMusic #'(voiceA voiceB) {
   \key c \major
   \time 4/4

        \repeat volta 2 {
                c4 c c c  | %voiceA measure 1
                c,4 c c c | %voiceB measure 1
        }

        \repeat volta 2 {
                g4 g g g  | %voiceA measure 2
                g,4 g g g | %voiceB measure 2
        }

}

\score {
        \new StaffGroup <<
          \new Staff << \relative c'' \voiceA \\ \relative c'' \voiceB>>
        >>
        \layout { } %emits four measures
}
