Well, I'm not an advanced user but I'll give a try :))

Try putting 'EventChord in the place of 'RequestChord around line 18:

It seems to be working here... (lily 1.7.24 and latest cvs code)
maybe the FIXME in this file can be deleted?

#(set-chord-name-style 'jazz) code that seems not to be necessary
anymore. The "corrected" code (or at least compilable :)) is as
follows. I couldn't find "" thought.

scheme = \chords {
  % major chords
  c:6           % 6 = major triad with added sixth
  c:maj         % triangle = maj
  c:6.9^7       % 6/9 
  c:9^7         % add9

  % minor chords
  c:m           % m = minor triad
  c:m6          % m6 = minor triad with added sixth
  c:m7+ % m triangle = minor major seventh chord
  c:3-.6.9^7    % m6/9 
  c:m7          % m7
  c:3-.9        % m9
  c:3-.9^7      % madd9

  % dominant chords
  c:7           % 7 = dominant
  c:7.5+        % +7 = augmented dominant
  c:7.5-        % 7b5 = hard diminished dominant
  c:9           % 7(9)
  c:9-          % 7(b9)
  c:9+          % 7(#9)
  c:13^9.11     % 7(13)
  c:13-^9.11    % 7(b13)
  c:13^11       % 7(9,13)
  c:13.9-^11    % 7(b9,13)
  c:13.9+^11    % 7(#9,13)
  c:13-^11      % 7(9,b13)
  c:13-.9-^11   % 7(b9,b13)
  c:13-.9+^11   % 7(#9,b13)

  % half diminished chords
  c:m5-.7               % slashed o = m7b5
  c:9.3-.5-     % o/7(pure 9)

  % diminished chords
  c:m5-.7-      % o = diminished seventh chord

\score {
  \notes <
    \context ChordNames {
%       #(set-chord-name-style 'jazz)
        \scheme }
    \context Staff \transpose c c' \scheme

I'm not an expert on that, but the viola parts I usually play return
to the initial clef. I'll check other (and more reliable) editions
thought.  Meanwhile, how about uncommenting the line that set the
notes of the horn to the right size? (\property Staff.fontSize\unset)

I'm sorry but I couldn't get this one to work :(( But ... since "If
possible, avoid this feature [outputproperty]: the semantics are not
very clean, and the syntax and semantics are up for rewrite" (user's
manual) why not change the example to something nicer like:

\context Staff \notes\relative c''{
\once \property Score.RehearsalMark
            \set #'extra-offset = #'(-0.3 . 3.0)
        \mark A
        \mark B

my vote would be for less space
