Re[2]: avoid merging stems

[musicus]

so \voiceXxx should work, or not?
Why doesn't the stem of "\voiceOne g" go up as intended? Sure, it's a 
quite rare usecase, but i hope you can see my point.
I don't want to merge the \voiceOne and \voiceTwo stems and if you try 
to hide/ omit one of both stems, both disappear!
That's why I'm asking...
Anyway, in this case the chord syntax {<g g>4 bes g} does work 
perfectly.

Thanks for help,

      <<
            \clef bass \time 3/4
            \relative c' {\voiceOne g2.} \\
            <<
                  \relative c {\voiceTwo g4} \\
                  \relative c {\voiceFour g( bes g)}
            >>
      >>
}
