Re: unexpected result with keymap inheritance

Since `key-binding` checks global-map after the buffer-local map anyway,
putting global-map as the parent of your buffer-local map has basically
no effect.

This does not *remove* a binding from child-map.  Instead it marks the
key as unbound, thus hiding any potential corresponding binding in
parent keymaps.

Emacs does not provide a "remove binding" operation on keymaps.

Here the binding was not found in the buffer-local map but in the global
map instead.
