Right.  It would also be nice to keep the shell prompt in sync when you
run an Emacs command:

         (progn
           (comint-simple-send process (concat "# " command "\n"))
           (apply command-symbol (cdr command-list)))

But it looks like that might not get into the input history (see 
comint-input-history-ignore).

I think you could use the kshell/foo approach to provide required arguments
that can be inferred from the context (current directory, etc.).
