New issue 3893 by address@hidden: Patch: More readable \displayMusic  
output.
http://code.google.com/p/lilypond/issues/detail?id=3893

More readable \displayMusic output.

* Omit unnecessary optional arguments.
* Use rationals when printing moments (but not with grace parts, because  
that's ambiguous).

It would be nice to make the pretty-printed output smarter about newlines  
too, e.g:

(make-music 'NoteEvent
  'duration (ly:make-duration 2)
  'pitch (ly:make-pitch 2 3))

...but the ice-9 pretty-printer isn't customizable without shipping a  
modified copy. I don't think it's worth the bother.
