Now that the engraver is working correctly, do you still need this
change ?
I think the test against 'start' and 'end' was there to better estimate
the height of just what is on the currently-considered line.  If you
bypass this test, then sometimes the page breaking will be fooled :

\paper {#(set-paper-size "a6" 'landscape) }
\new PianoStaff <<
  \new Staff \relative f'' {
    c4 c c g a a g2 | e'4 e d2 | c2 r2
    c4 c c g a a g2 | e'4 e d2 | c2 r2
  }
  \addlyrics {
   Old Mac Don -- ald had a farm, in O -- hi -- o. \set stanza = "1."
   On that farm he had some cows, in O -- hi -- o. }
  \addlyrics {
   \repeat unfold 11 \skip1 \set stanza = "2."
   On that farm he had some pigs, in O -- hi -- o. }
  \addlyrics {
   \repeat unfold 11 \skip1 \set stanza = "3."
   On that farm he had some dogs, in O -- hi -- o. }
  \addlyrics {
   \repeat unfold 11 \skip1 \set stanza = "4."
   On that farm he had some ducks, in O -- hi -- o. }
  \addlyrics {
   \repeat unfold 11 \skip1 \set stanza = "5."
   On that farm he had some sheep, in O -- hi -- o. }
  \new Staff {
    \clef bass
    c1 f2 c2 c2 g2 c1
    c1 f2 c2 c2 g2 c1
  }

We should stop lyrics from breaking through span bars at the stage where
horizontal spacing constraints are determined, when we should have
start=0 and end=INT_MAX because the whole score is conceptually one long
line at that point.
