Yes, this is much clearer than the text in the Reference Manual.
Maybe something like this could be added to the Reference Manual
to say explicitly that the variable's value is a function?

I suggest to close this issue here because I am discussing related
problems in a different thread (bug#4816). I reported bug#4817
separately because I considered it a mere documentation issue.

Thanks for explaining select-safe-coding-system-accept-default-p,
your explanations answered my questions much better than the
documentation did.
