2.5.23, lilypond-book missing right margin

[Graham Percival]

Using the same sample .lytex file, the right margin is nonexistant; the 
bar line
of the example comes directly on the right-hand edge of the paper.  The 
left-hand
margin looks suspiciously big; is the right-hand margin getting added 
to the left-hand
margin by mistake?
