To be more credible, here is my try at doing this with a music function:

sust =
#(define-music-function (parser location note rhythm lasts music)
  (ly:pitch? ly:duration? ly:duration? ly:music?)
  #{ <<
      \mergeDifferentlyDottedOn
      { \voiceOne $note $rhythm $music }
      \new Voice { \voiceTwo $note $lasts }
  >> #})

\new Staff {
   \sust f' 16 4 \sust g' 16 8. \sust a'16 8 b'16
}

Hmm.  Is it only my impression, or had music functions became easier to write?

Anyway, this is quite concise.  However, voice "direction" is
hardcoded... probably this could be changed?
Also, without explicit Staff the output is crazy.  No idea whether
this is easy to fix.

cheers,
