Confirmed! Thank you Herbert.

I moved the two index opening commands from the end of the sectioning
command to the start of the standard text that follows the sectioning
command, which eliminated the symptom.

My one remaining worry is that, with bad luck and just the wrong
vertical alignment, the section header might fall at the bottom of the
page *before* the page pointed to by the index entry. But so far, I
seem to be having the opposite problem (section header falling *after*
the page pointed to by the index entry, but only with my compile
script, not with eyeballs) so I have to do more research.

Thanks for your help on this. It solved the worst of my two index
problems.
