Hmm, that example seemed very complicated, I couldn't make out what was
going on - but I did just find NoteColumn.force-hshift just a little
further on (in
http://www.lilypond.org/doc/v2.18/Documentation/notation/multiple-voices
) and it seems to do the trick:


\version "2.18.0"

MI = {\voiceOne  a4.~  \once \override NoteColumn.force-hshift = #1.7 a8
b c'}

MII = { \voiceTwo a8 g^~  <e_~ g^~ >8 <e g> \skip 4 }

\new Staff   << 
 \new Voice \clef bass \time 6/8 \MI       
 \new Voice   \MII                    
>>

Ironically, I had already tried \\override NoteColumn.X-offset without
effect...
