My preference would be to put this at the end of font-table.ly:

displayFontSet =
#(define-music-function (parser location set) (scm?)
  #{
     \markuplines \override-lines #'(word-space . 4)
              \doc-chars  $set
   #})

Then you'd have

@lilypond
\include "font-table.ly"
#clefs
@end lilypond


Note: I haven't tried this yet.

Thanks,
