That would explain why the problem went away when I made a pretty
minor change to the lilypond.  But it makes me nervous that this can
pop up at any time.  (I think it happened when I added the custos, but
it might have been the incipit.)

I've thought about using that, and it does in fact fix this particular
problem.  But some of the people I play with used to complain when
abc2ps would break a line in the middle of a "beat" (in this case, a
half note), so I was thinking of the fact that lilypond puts in an
invisible bar every so often as a feature.  So if I did barAlways, I
would have to check this carefully, and that's the kind of thing
computers should do for you.

So I tried changing the line width to 400 pt instead of 390 with the
geometry package, and lilypond-book crashed on me:

Here's the lytex file that did that:
