Re: map-keymap doc not clear

[Richard M. Stallman]

    The problem is that
    "binding" sometimes means the command (or keymap) that an event is bound to,
    and it sometimes means the pair: event plus what it's bound to.

It is traditional to use the term "binding" in both ways.
I don't think it is desirable to change this double usage,
which is much broader than Emacs.

If someone comes up with a better way to improve this doc string, we
can use it.  Otherwise I'll install my change.
