LSR inconsistencies

[Werner LEMBERG]

I've found some LSR inconsistencies.  All of the following snippets
are tagged as `docs' and approved but missing in the lilypond git
repository (while present in the LSR bundle).

  #1033 
(customize-drumpitchnames,-drumstyletable-and-drumpitchtable-in-layout-and-midi.ly)
  #1069 (tam-tam-example.ly)
  #1071 (percussion-example.ly)
  #1083 (appogiatura-or-grace-note-before-a-bar-line.ly)

    Wrong word in title, BTW: appogiatura → appoggiatura

  #1084 (of-the-ubiquity-of-markup-objects.ly)
  #1087 (adding-or-modifying-script-articulations.ly):

    It contains the line

      %% Apparently this requires 2.19 or higher.
