Stefan, I forgot to put you on the CCs here -- I wondered whether you
had any ideas here. I think lifting this out of
`execute-extended-command' should be possible -- either by doing
something a la
(run-at-time 0 nil (lambda ()
(with-temp-message "The binding is foo"
(sit-for 1))))
or making `execute-extended-command' set a variable and do the messaging
from the "command loop" after running post-command-hook.
