Now I have found a way (modelled after `latex-fill-nobreak-predicate' in
tex-mode.el):

(defun fill-open-link-nobreak-p () 
  "Don't break a line after an unclosed \"[[link \"."
  (save-excursion
    (skip-chars-backward " ")
    (let ((opoint (point))
	  spoint inside)
      (save-excursion
	(beginning-of-line)
	(setq spoint (point)))
      (when (re-search-backward "\\[\\[" spoint t)
	;; (message "found") (sit-for 2)
	(unless (re-search-forward "\\]\\]" opoint t)
	  (setq inside t)))
      inside)))

(add-to-list 'fill-nobreak-predicate 'fill-open-link-nobreak-p)

Next open issue: How can I use this mechanism to prevent Emacs from
breaking lines starting with "*" or "#"?
