There was a bug report for tmux which would be the right place to cite.

That's interesting, since st provides a corrupt file :-)

Essentially the problem was that they added capabilities which are
supposed to have values, I made one fix but overlooked another.
(The tic/infocmp programs didn't handle the case well when st's
terminal entry said a value was a boolean and another entry said it was
a string).

The most recent terminal database at the webpage fixes that (by
eliminating the defects from st' terminfo file)

(subsequent database updates aren't _there_ since they won't work
with the vanilla ncurses 6.1 - long story).

That would be a bad idea, since st's developers haven't fixed their
terminfo bug (more than two years).  If you do that, there's no point
in discussing the results on this list.

bye.
