Could you explain why you need `keymap-unset-key` and why you need to
lookup "all but the ignore the parent"?

I'm curious because the meaning of these can be subtly more complex than
meets the eye once you consider things like `make-compose-keymap`.

Hmm... if you need to add yet-another-arg to `Flookup_key`, than I'm not
sure it qualifies as "the infrastructure is actually there already."

BTW, `map-keymap-internal` could be another way to attack the problem
(it has other downsides, but it stops before entering the parents).
