I've now done this, and tested with all of the examples in this file
(and also in a couple of real-life texinfo files), and this approach
seems to work (and solves the original reported problem).  (I also made
'C-x n d' narrow to the current node, because that's something I've
missed for years, but it's unrelated.)

Let me know if I broke anything.
