Doc 2.4.2: Indicating harmonics and dampened notes

[Pierre Perol-Schneider]

Hi Bug Squad,
See:
http://lilypond.org/doc/v2.18/Documentation/notation/guitar.html#indicating-harmonics-and-dampened-notes
And:
http://lilypond.org/doc/v2.19/Documentation/notation/guitar.html#indicating-harmonics-and-dampened-notes

1. I don't understand the reason to put the NoteHead defs at a Staff level.
2. Maybe a whole note is not the best example to show the 'harmonic-mixed
result.

How about changing this snieppet:

\relative c' {
  \clef "treble_8"
  \override Staff.NoteHead.style = #'harmonic-mixed
  d^\markup { \italic { \fontsize #-2 { "harm. 12" }}} <g b>1
}

To:

\relative c' {
  \clef "treble_8"
  \override NoteHead.style = #'harmonic-mixed
  d8^\markup { \italic { \fontsize #-2 { "harm. 12" }}} <g b>4
}

Cheers,
Pierre
