I believe I've fixed all of the mentioned issues in this new
patch. Apologies for having not gotten it correct the first time; I'll
keep in mind to better review before sending in the future.

Subject: [PATCH] Fix uses of (call-interactively) in
 lisp/emacs-lisp/checkdoc.el

Passing the prefix argument as the 3rd argument to 'call-interactively'
causes the prefix argument to be interpreted as events, which is not
only wrong, but also causes a type error, as 'current-prefix-arg' can
never be a vector as 'call-interactively' expects.  'call-interactively'
automatically passes its prefix argument to the called function, so just
do that, eliminating faulty behavior.

* lisp/emacs-lisp/checkdoc.el (checkdoc-ispell)
(checkdoc-ispell-current-buffer)
(checkdoc-ispell-interactive)
(checkdoc-ispell-message-text)
(checkdoc-ispell-start)
(checkdoc-ispell-continue)
(checkdoc-ispell-comments)
(checkdoc-ispell-defun):
Do not pass 'current-prefix-arg' to 'call-interactively' as an event
vector; merely allow it to propagate forward to the interactive call.
