This was intended to address TODO items in `other-frame-window`.
The first TODO item:

;; - Pay attention to bindings added to ctl-x-4-map and ctl-x-5-map

can be solved by just leaving the existing ctl-x-4-map and ctl-x-5-map
as they are now.  And by adding to these maps the [remap t] fallback
bound to the `ofw--set-prefix` command it would be possible to use key bindings
from `ofw-transient-map` where keys don't need to be bound to special
-other-window variants.

And when no key is found in `ofw-transient-map`, then the global binding
could be appled.  For example, `C-x 4 C-h i' could show the Info manual
in another window.
