Alignment bug?

[Hilary Snaden]

A few days ago I mentioned problems with tweaking the vertical alignment 
of notes. I've now tried everything I can think of, as well as some 
suggestions from others, but none of the tweaking works reliably (or at 
all) if there are more than two voices on a staff.

Ex.1 is a satisfactory rendering, coded in two voices. Ex.2, 3 and 4 are 
attempts using three voices, all horribly misaligned.

\score {
  \new Staff {
    \clef bass \key c \major \time 4/4
    \set Staff.instrumentName = "Ex.1"
    <<
      \new Voice { \voiceOne s1 \once \override NoteColumn 
#'force-hshift = #0.3 e2 \once \override Tie #'Y-offset = #'1.2 f ~ 
\once \override NoteColumn #'force-hshift = #0.5 f e }
      \new Voice { \voiceTwo <a^~ c_~ f,_~>1 <a c f,> <g c c,> }
    >>
  }
}

\score {
  \new Staff {
    \clef bass \key c \major \time 4/4
    \set Staff.instrumentName = "Ex.2"
    <<
      \new Voice { \voiceOne s1 \once \override NoteColumn 
#'force-hshift = #0.5 e2 f ~ \once \override NoteColumn #'force-hshift = 
#0.5 f e }
      \new Voice { \voiceTwo a1 ^~ a g }
      \new Voice { \voiceTwo <c f,>1 ~ <c f,> <c c,> }
    >>
  }
}

\score {
  \new Staff {
    \clef bass \key c \major \time 4/4
    \set Staff.instrumentName = "Ex.3"
    <<
      \new Voice { \voiceOne s1 \once \override NoteColumn 
#'force-hshift = #0.5 e2 f ~ \once \override NoteColumn #'force-hshift = 
#0.5 f e }
      \new Voice { \voiceTwo a1 ^~ a g }
      \new Voice { \voiceFour <c f,>1 ~ <c f,> <c c,> }
    >>
  }
}

\score {
  \new Staff {
    \clef bass \key c \major \time 4/4
    \set Staff.instrumentName = "Ex.4"
    <<
      \new Voice { \voiceOne s1 \voiceThree \once \override NoteColumn 
#'force-hshift = #0.5 e2 f ~ f e }
      \new Voice { \voiceTwo a1 ^~ a g }
      \new Voice { \voiceFour <c f,>1 ~ <c f,> <c c,> }
    >>
  }
}
