I think the first `describe-key` above should always use
`current-buffer` (that's the whole point of the function: to lookup the
keybinding in that other buffer).

And for the second, it's supposed to be a fallback that does whatever
`describe-key` does normally, so I don't see why we'd need/want this
(if ...) construction.

OTOH we should probably try and change the `key` arg to use the new
key-list format expected by `describe-key` (i.e. a list of (SEQ
. RAW-SEQ) pairs).

Same here.
