I'd like to add to this bug report (single voice using a variable):

%%%%%%%%%%%%%%

altoOneVoice = \relative {
   d'2\melisma e4\melismaEnd cis
}

altoTwoVoices = \relative {
    <<
      { d'2\melisma e4\melismaEnd cis }
      \new Voice { \voiceTwo s1 }
    >>
}

altText = \lyricmode {
    side, sit
}

\markup \column { "One voice in a music variable" "(center-aligned 
melisma)" }
\score {
    <<
      \new Staff \altoOneVoice
      \addlyrics \altText
    >>
}

\markup \column { "Two voices in a music variable" "(no melisma at all)" }
\score {
    <<
      \new Staff \altoTwoVoices
      \addlyrics \altText
    >>
}

% same music as above, but explicitly written out in the \score block
\markup \column { "One voice explicitly written out in \score block" 
"(left-aligned melisma)" }
\score {
    <<
      \new Staff \relative {
        d'2\melisma e4\melismaEnd cis
      }
      \addlyrics \altText
    >>
}

% same music as above, but explicitly written out in the \score block
\markup \column { "Two voices explicitly written out in \score block" 
"(left-aligned melisma)" }
\score {
    <<
      \new Staff \relative {
        <<
          { d'2\melisma e4\melismaEnd cis }
          \new Voice { \voiceTwo s1 }
        >>
      }
      \addlyrics \altText
    >>
}

%%%%%%%%%%%%%%
