And to avoid cutting a sorry figure like this one in the future, I've 
written a
snippet of code to highlight arguments in Info mode, too, and I'm 
attaching it.
Arguments are empirically identified as symbols of two or more uppercase
letters, digits or dashes, starting with a letter.

I would have preferred using the `help-argument-name' face, but on my
installation this face misbehaves (I've filed a bug report), so I'm using
`font-lock-comment-face'.


(defun rr-Info-mode-highlight-argument-names ()
  "Highlight argument names as they are highlighted in Help mode."
  ;; To avoid highlighting uppercase single letters in the text, highlight
  ;; only symbols more than one character long.
  (font-lock-add-keywords nil
                          '(("\\_<[A-Z][-A-Z[:digit:]]+\\_>"
                             . font-lock-comment-face))))

(add-hook 'Info-mode-hook #'rr-Info-mode-highlight-argument-names)
