   You mean "C-h b", I suppose.

Yes (but I'm used to seeing them in C-h m output).

   He already did, see

   Bottom line: they were deemed unnecessary, since the key bindings that
   use the prefix also show the prefix.

Thanks.

   We could add a user option to get that back, if we think people will
   want that sometimes.

I would prefer that, since it's what I'm used to.  I would argue that
the default should be on, since it almost tripped me up once.  But it's
probably more of a legacy thing, and in any case I suppose that ship has
sailed.

   If adding the option is deemed desirable, I'd be happy to code it.
