OK, I started some research.

I fixed exactly this problem for LM 4.5.3 on
13/9/2009 by adding line-width = 5.5\in to the
@lilypond[] commands which invokes these examples.
That was effective at the time, but the lilypond
book settings of line-width are now overridden by
the insertion of line-width = 5.5\in - 2.0 * 0.4\in.

That line was not being inserted last Sept -
it renders all explicit settings of line-width
in the @lilypond[] command ineffective.

The change happened sometime after 2.13.4-1.  I'll
try to narrow down when it happened more closely.
