Looking at this:

(defun syntax-propertize-multiline (beg end)
  "Let `syntax-propertize' pay attention to the syntax-multiline property."
  (when (and (> beg (point-min))
	     (get-text-property (1- beg) 'syntax-multiline))
    (setq beg (or (previous-single-property-change beg 'syntax-multiline)
		  (point-min))))
  ;;
  (when (get-text-property end 'syntax-multiline)
    (setq end (or (text-property-any end (point-max)
				     'syntax-multiline nil)
		  (point-max))))
  (cons beg end))

And some of the usage sites...  I'm still not quite sure what the
semantics here are.  :-)  I've added Stefan M to the CCs; perhaps he can
explain and I'll write something up for the manual?
