    >From the docstring I understood that "valid key sequence" means
    a valid and bound key sequence, due to the sentence:

      The number is how many characters at the front of key it takes
      to reach a non-prefix command.

I will change that to say "a non-prefix key".
But you know you really should look at the manual
in cases like this.

    However, if this is not what the docstring meant, and leaving the logic
    of the current return value is desirable, then maybe `lookup-key' needs
    an additional argument defining another logic of its return value.

Why?

    Otherwise, almost all code in `lookup-key' should be duplicated in
    `shadow_lookup'.

Why?
