Unexpected extra measure at end

[Arjan Bos]

Dear list,

When creating a score for the choir I'm in, I found out that Lilypond 
generates an extra measure at the end when the lyrics are defined 
within the voice. When they are just outside the closing `}' of the 
voice, the resulting pdf looks the same, except the empty bar at the 
end has gone.
Is this a bug?

This is the (almost) smallest example I could come up with that still 
has the problem.


%% -- sniplet begins here
\version "2.4.2"

tenMusic = \notemode  { \relative c' { c4 c c c } }
tenText  = \lyricmode { E -- tra bar. Why? }

\score {
  \context ChoirStaff {
    <<
      \context Staff = "ten" {
        \context Voice = "tenors" { \tenMusic }
        %% When put here, the lyrics generate an extra measure at the
        %% end. If they are outside the Voice brackets, it doesn't.
        \context Lyrics = tenorsA { s1 }
      }
      \context Lyrics = tenorsA \lyricsto tenors { \tenText  }
    >>
  }
}

%% --- sniplet ends here

TIA,

Arjan

It was funny how people were people everywhere you went, even if the 
people concerned weren't the people the people who made up the phrase 
"people are people everywhere" had traditionally thought of as people. 
And even if you weren't virtuous, as you had been brought up to 
understand the term, you did like to see virtue in other people, 
provided it didn't cost you anything.
