Thanks; that worked.  It seems, though, that I should have been able to
achieve the same effect with forcing a positive hshift on the B in the
lower staff (which is actually closer to the printed score), but when I
tried it I could not see that the note moved at all.

Searching the documentation turns up

And it looks like the lower-staff B has moved anyhow; hmm….  Okay, I
think this has given me some insight into what force-hshift is actually
doing.

Thank you,
