But while using separate voices, LilyPond prints the instrumentCueName
twice, too.
Or did I sth wrong?

\version "2.16.0"

\addInstrumentDefinition #"piccolo"
  #`((instrumentName . "Piccolo")
     (shortInstrumentName . "Pc.")
     (instrumentCueName . "Piccolo")
     (midiInstrument . "piccolo"))

\new Staff
<<
\new Voice {
        \voiceOne
        e''2 e'' g'' a'' g''
        }
\new Voice {
        \voiceTwo
        c''2 c'' e''
        \override InstrumentSwitch #'direction = #DOWN
        \instrumentSwitch "piccolo"
        c'' c''
}
