I had a change to this code sitting waiting to make, and when I tried
it, it fixed this problem.  It removed some code (which I'd added
myself in the past), and in this case simpler is evidently better.

So I've commited the change, rather than waiting until after the next
release, as I'd previously intended.

Please let us know if the change works ok with your manual and if there
are any regressions.
