ok, i've come up with this so far:

\score {
    \notes \relative c' {
        \context Staff { <<
            \context Voice { << \tieUp g'~  e'~ >> << g,  e' >> }
            \new Voice  {
                \tieDown \property Voice.Stem \override #'transparent = ##t
                \property Voice.NoteHead \override #'extra-offset =  #'(-2.35 . 
0)
                \property Voice.Tie \override #'extra-offset = #'(-2.35 . 0)
                f,~f  }
        >>  }
    }

    \paper {  raggedright = ##t
          }
}

it works, but is rather full of manual fudging for my taste. there must be
a more elegant way.

thanks in advance for any suggestions!
