What to do with snippet "Centering markup on note heads automatically"?

[Thomas Morley]

Hi all,

http://lists.gnu.org/archive/html/lilypond-user/2016-03/msg00302.html
states correctly that the LSR-snippet "Centering markup on note heads
automatically"
http://lsr.di.unimi.it/LSR/Item?id=637
doesn't work in 2.19.x anymore.
It's tagged doc, so it appears in snippets.

It turns out that the custom-engraver, setting TextScript-parent to
NoteColumn, is unnecessary in 2.19. (NoteColumn is already x-parent)

Sufficient would be to do (deleting the engraver and other settings):

\layout {
  \context {
    \Voice
    \override TextScript.self-alignment-X = #CENTER
    \override TextScript.parent-alignment-X = #CENTER
  }
}


Though, what to do?
Creating a snippet in snippets/new
or
simply remove the doc-tag in LSR?

Opinions?

Cheers,
  Harm
