align-on-syllable.ly and 2.19.36

[David Wright]

Hi, I think I've got the latest version of align-on-syllable.ly
(3049 Dec  4 02:21) from variously

https://lists.gnu.org/archive/html/lilypond-user/2015-12/msg00124.html

and it works great in 2.18.2. However, I'm having problems using it in
2.19.36. I added the following LP code involving NullVoice to the test
case, which breaks it.

I don't know if it's the fault of NullVoice or align-on-syllable.ly.
NullVoice is rather delicate; for example, it doesn't play well with
\addlyrics for no reason obvious to me.

\score {
  \new Staff <<
    \new NullVoice = "nullvoice" \melody
    \new Voice = "voice" \melody
    \new Lyrics = "testI" 
      \with { \override LyricText.X-offset = #center-on-word }
      \lyricsto "nullvoice" \lyr
    \new Lyrics = "testII" 
      \with { \override LyricText.X-offset = #center-on-word }
      \lyricsto "nullvoice" \lyrA
    %% The control-voice omits the override
    \new Lyrics = "control" 
      \lyricsto "nullvoice" \lyrControl
  >>
  \layout {
    \context {
      \Score
      lyricMelismaAlignment = #-0.6
    }
  }
}

Cheers,
David.
