Too bad the code got messed up. Here is a (hopefully) clean version:
%%%%%%%%%%
\version "2.18.2"
% test for setting slash chords with realbookchords font

chExceptionMusic = {
  <c e g bes>1-\markup { "7" }
  <c ees g>1-\markup { ">" }
}

chExceptions = #(append
                  (sequential-music-to-chord-exceptions 
chExceptionMusic #t)
                  ignatzekExceptions)

\score {
  \new StaffGroup <<
    \chords {
      \override Score.ChordName.font-name = #"New Real Book Chords"
      \set chordNameExceptions = #chExceptions
      \set slashChordSeparator = "/"
      f2.:m c:7/e
    }
    \new Staff { \key aes \major \time 3/4 c'4 aes'2 c'4 bes'2 }
  >>
  \layout {}
}
%%%%%%%%%%%%%
and once attached, just in case.

Yours, Simon
