Comment #5 on issue 1473 by k-ohara5...@oco.net: Allow ottavation markings  
to affect voices only
http://code.google.com/p/lilypond/issues/detail?id=1473
I think desired behavior is exactly that from Neil's suggestion in the  
original thread, which I'm paraphrasing below.  It would be more convenient  
if a built-in function (maybe \ottavaVoice #1 ) would set the  
appropriate "8va" text, direction of the bracket, and the shift  
of "middleCPosition" for us.

\score {
  \new Staff << {
    r4

    \set Staff.ottavation = #"8va"
    \once \override Staff.OttavaBracket #'direction = #UP
    \set Voice.middleCPosition = #(+ -6 -7)  % one octave down from the  
usual #-6

    fis''' r gis''' r fis''' r gis'''

    \unset Staff.ottavation
    \unset Voice.middleCPosition

    <e'' a''>1
