Finally got emacs-wiki highlighting just the way I want it.
Apparently, it bypasses the normal font-lock thing. Changes: I made
the example tag remove all the properties from the bounded region.
Here’s the relevant snippet from my ../emacs/emacs-wiki-config.el:

(defun sacha/htmlfontify-insert-region (buffer begin end)
  "Insert into BUFFER the htmlified text between BEGIN and END."
    (let* ((hfy-optimisations (cons 'skip-refontification hfy-optimisations))
	   (input-text (buffer-substring begin end))
	   (temp-file (make-temp-file "html-input"))
	(insert input-text)
	(setq buffer-file-name temp-file)
	(save-excursion (setq output-buffer (htmlfontify-buffer nil nil)))
	(set-buffer-modified-p nil))
	  (let (b e yanked-output)
	    (set-buffer output-buffer)
	    (goto-char (point-min))
	    (search-forward "
	    (setq b (line-beginning-position))
	    (goto-char (point-max))
	    (search-backward "

(forward-line -1)
(setq e (line-beginning-position))
(setq yanked-output (buffer-substring-no-properties b e))
(set-buffer buffer)
(insert yanked-output))
(set-buffer output-buffer)
(set-buffer-modified-p nil)
(delete-file temp-file)
(kill-buffer output-buffer)))))

(defun sacha/emacs-wiki-example-tag (beg end attrs highlight-p)
"Mark up text as an example with optional font-locking."
(if highlight-p
beg end '(face nil font-lock-multiline nil
invisible nil intangible nil display nil
mouse-face nil keymap nil help-echo nil))
(goto-char end))
;; I don't know what would happen if you don't have
;; htmlfontify. I guess if you are installing this you
;; should have it...
(let ((end-marker (set-marker (make-marker) (1+ end))))
(narrow-to-region beg end)
(let* ((mode (cdr (assoc "mode" attrs)))
(start (progn (forward-line) (point)))
(stop (progn (goto-char end) (beginning-of-line) (point)))
(text (buffer-substring-no-properties start stop))
(buffer (current-buffer)))
(delete-region beg end)
(insert text)
(when (and mode (and (stringp mode) (functionp (intern mode))))
(funcall (intern mode))
(sacha/htmlfontify-insert-region buffer (point-min) (point-max)))
(goto-char (point-min))
(insert "

	  (goto-char (point-max))
	  (insert "

(add-text-properties (point-min) (point-max)
'(rear-nonsticky (read-only) read-only t))))
(goto-char end-marker))))

(add-hook 'emacs-wiki-mode-hook 'emacs-wiki-highlight-buffer t)
