I have taken a look how the command loop does this right now.  It
appears that read-key-sequence does all the lookup (and it is more or
less necessary to do so in order to decide when a key sequence is
finished), stuffs the looked-up command as a by-product into an
internal variable that appears not accessible at the Lisp level (at a
first glance), and the command loop picks it out from there.

Of all the ugly...

Factoring the keymap and partial keymaps out into a separate function
would probably not be trivial.  But even if code reuse might not be
practical, I think that something like posn-key-binding should be
implemented in keyboard.c so that there is some guarantee it will
deliver the same results.
