Simple check.
While editting in the buffer, I checked the word count using
M-x count-words
This works well. I then added some more text into the buffer and used the
C-x ESC ESC to rerun the command. "repeat-complex-command"
But the following error is displayed in the mini-buffer.
"eval: Wrong type argument: integer-or-marker-p, nil"
I expected the C-x ESC ESC to perform without error just as if I entered the
M-x count-words
What should be expected here?

count-words is an interactive function: (count-words START END)
It count words between START and END, if called interactively, START and
END are the start and end of the buffer (if there is no active region).
If called from Lisp, it returns the number of words between START and
END, *without printing any message*.
If you use `repeat-complex-command' to perform the last command, it will
use `(count-words nil nil)'. nil is not an integer or a marker, so an
error arises.

I'm not sure whether it is a bug or a feature here.

A bug.
(called-interactively 'any) returns nil here, so the code then calls
`narrow-to-region' with START and END each nil.

Thank you. I have filed a bug report #14136.
