Although I made a minor fix in 2023 for asciidoctor builds, I missed
an earlier regression from 2020 that had been fixed locally in the
Debian package but not upstream.  I'm sending 2 more fixes that should
make all manual pages build properly with asciidoctor.

However, given that asciidoctor support has been broken upstream for
nearly 5 years now, it might make more sense to remove it instead.  We
only moved to asciidoctor in Debian to remove a Python 2 dependency.
Since asciidoc was ported to Python 3 that's no longer a concern.
