Ah, that's embarrassing. Rereading the manual I see this
important bit that I have forgotten:
You can get a list of subcommands for a particular prefix key by
typing C-h, ?, or F1 (describe-prefix-bindings) after the prefix
key. (There are a few prefix keys for which not all of these keys
work—those that provide their own bindings for that key. One of
these prefix keys is ESC, because ESC C-h is actually C-M-h,
which marks a defun. However, ESC F1 and ESC ? work fine.)
I guess this is working as intended, then? I was thinking of the
recommendation in the style guide, which I have read many times more
than the manual:
Don’t bind C-h following any prefix character (including
C-c). If you don’t bind C-h, it is automatically available as
a help character for listing the subcommands of the prefix
character.
