pre/post-command-hook is run by the command *loop*, not by call-interactively.
The command loop is the chunk of C code which does something like:
(while t
(let ((keys (read-key-sequence)))
(run-hooks 'pre-command-hook)
(call-interactively (key-binding keys))
(run-hooks 'post-command-hook)
(redisplay)))
We don't want call-interactively to run those hooks, because commands
may internally call call-interactively themselves.
