And now that users want some good news "successful completion" messages, we
still want it to be separate from the program output on stdout.  I still want 
to use :

  \displayLilyMusic \transpose f d \relative c' {
    \key des\major
    des\p\< f as des\f
  }

What does Lilypond currently put on stdout ?
The output of \displayLilyMusic and \displayMusic; anything else?
