Hi Paul,
There was some confusion on my side WRT undesired page/column
breaks.
While testing the added checks in cleverefcheck.pl, I saw too
many potential such cases flagged. This made me do some tests
to reproduce unfortunate page/column breaks.
There are three such patterns I have confirmed.
1. "listing" environment (with contents of fancyvrb) next to proper
LaTeX headings (\chapter, \section, \subsection, etc.)
2. Any environment (not necessarily float) next to QQA heading
of "Answer:"
3. Any environment (not necessarily float) next to epigraph
This means commit f106e0e6dc43 ("defer/rcuusage: Move float objects
away of section titles") has no merit. It is safe to revert it if
you'd like. I was confused by patterns 2 and 3 and thought that
floating objects can cause undesired breaks.
Patches 1/4--3/4 add tests in cleverefcheck.pl that check patterns
listed above respectively.
Patch 4/4 fixes problematic places flagged by the updated script.
Feel free to wordsmith the leading phrases I added in QQAs.
Thanks, Akira
