Line breaks and glissandos in \version "2.11.22"

[Bernard Hurley]

Hi,

After processing following code:

===============
{
  \time 4/4
  r2 d''2\glissando
  \break
  c''2 r2
}
===============

there is no break between the two bars. I have a score with _lots_ of
glissandi accross bar lines. I need to be able to force line breaks. How
do I do it?

I have tried:
==========
\new Voice \with {
  \remove "Forbid_line_break_engraver"
}
{
  \time 4/4
  r2 d''2\glissando
  \break
  c''2 r2
}
==========
but it doesn't work!
