Ah, that one's hiding a bit.  I see it's as easy as say

(add-hook 'texinfo-mode-hook
          (lambda ()
            (set (make-local-variable 'fill-nobreak-predicate)
                 (lambda ()
                   (string-equal (buffer-substring (- (point) 3) (point))
                                 "@: ")))))
