The GNU guidelines state (roughly): write to stdout what is asked for, and
to stderr what is not asked for.

  $ foo --bar
  Usage: foo [options] arg            <-- stderr
  $ foo --help
  Usage: foo [options] arg            <-- stdout

Given this line of reasoning, lilypond -dshow-available-fonts should write
the list to stdout.
