** The variable minor-mode-overriding-map-alist allows major modes to
override the key bindings of a minor mode. The elements of this alist
look like the elements of minor-mode-map-alist: (VARIABLE . KEYMAP).
If the VARIABLE in an element of minor-mode-overriding-map-alist has a non-nil value, the paired KEYMAP is active, and totally overrides the map (if any) specified for the same variable in minor-mode-map-alist.
minor-mode-overriding-map-alist is automatically local in all buffers, and it is meant to be set by major modes.
