Does Forbid_line_break_engraver still work?

[Carl D. Sorensen]

I'm trying to make a clear example for the GDP docs.

According to my understanding, Forbid_line_break engraver should eliminate
line breaks at measures where there is a tie generated by the
Completion_heads_engraver.

In the code below, I can't change where the line break is by including or
removing the Forbid_line_break_engraver.  I've tried changing the line-width
and the presence or absence of the Forbid_line_break_engraver.  As far as I
can see, there is no special requirement to avoid breaking on the tied
measure; it's just a standard bar line.

Any suggestions as to what I'm doing wrong?  Or is this just a bug?

Thanks,

Carl
