Here are two interesting functions for several reasons...
But the question: how can I avoid hard-coding the C-u key but
instead have the keybinding inserted thru a reference to the
function, i.e. `universal-argument'?
I don't plan to rebind C-u and/or use something else for
universal-argument, rather I'd like to just not have the C-u
hard-coded for personal/political reasons.
(defun open-irc (&optional connect)
(interactive "P")
(let ((irc-buffer (car (erc-buffer-list))))
(if irc-buffer
(progn
(switch-to-buffer irc-buffer)
(erc-scroll-to-bottom-no-blanks))
(if connect
(irc-connect-to-all)
(message "did nothing, C-u to connect") )))) ; [1]
(defun new-message (&optional force)
(interactive "P")
(message (format "%s" force))
(if (or (not (eq major-mode 'message-mode)) force)
(progn
(unless (gnus-alive-p) (gnus))
(gnus-post-news 'post "") )
(message "did nothing, C-u to force") )) ; [2]

You mean, in the `message' call? Have a look at
(info "(elisp) Keys in Documentation")

I have it working in docstrings but not in general, for
example this
‘\[COMMAND]’
stands for a key sequence that will invoke COMMAND, or ‘M-x
COMMAND’ if COMMAND has no key bindings.
sounds like what I want but
(substitute-command-keys "\[universal-argument]")
:(

You need to escape the backslash, otherwise \[ just becomes [ in the
string.
