I'm not sure I understand the reasons for each of the changes here.
char-tables are a tricky data structure, so I'd like to make sure this
change doesn't make our code subtly incorrect.
So could you please walk us through the proposed changes, adding
explanations for each part as you go?
(And what do char-tables have to do with describing key bindings,
btw?)

AFAICT, you didn't CC Kenichi; I have now added him to the discussion.
Thanks.
