Re: Broken TextSpanner does affect horizontal spacing

[David Nalesnik]

Note that this also happens with Hairpin.

\score {
  \relative c' {
    \override Hairpin.minimum-length = 50
    c4\< d e f
    \break
    c4 d e f
    \break
    c4 d e f\!
  }
  \layout {
    ragged-right = ##t
  }
}

Hairpin has the same sort of bounding grobs: NoteColumn for unbroken
bounds, NonMusicalPaperColumn for broken.  The middle line has
NonMusicalPaperColumn as both bounds.
