Completion heads engraver lyrics revisited

[Arvid Grøtting]

Boy, am I ashamed now.

I bug#578, I reported a regression in the way lyrics were handled when
attached to music typeset using the Completion_heads_engraver.  There
was indeed an ugly regression, but my description of the way the
lyrics *should* be typeset was wrong.

No regression this time, just an engraving nitpick:


% \version "2.15.12"

%  Lyrics in line two shouldn't line up with those in line
% one; rather, they should line up with those in line three.

mel = \relative c'' {
 c2 c1 c1 c2
}

lyr = \lyricmode {
 One -- two __ three -- four.
}

\score {
 \new Score <<
   \new Staff <<
     \new Voice = "normal" \mel
   >>
   \new Lyrics \lyricsto "normal" \lyr
   \new Staff <<
     \new Voice = "completion" \with {
       \remove "Note_heads_engraver"
       \consists "Completion_heads_engraver"
     } \mel
   >>
   \new Lyrics \lyricsto "completion" \lyr
   \new Staff <<
     \new Voice = "revisited" \relative c'' {
       c2 c~c c~c c
     }
   >>
   \new Lyrics \lyricsto "revisited" \lyr
 >>
}
