Nevermind... that's worse :)  It causes j to become a prefix key,
losing self-insert binding for j + any other key.

It seems like a specialized function will be needed that will capture
the next key and need to insert a j + resend the other key pressed to
the unread-command-events... I don't know if such a facility exists in
vimpulse, but would be easy enough to concoct... I'll post an example
in a bit
