Would the following work as a regexp builder that allows arbitrary space
and cookies between each word (making sure there is at least one)?

#+begin_src emacs-lisp
(defun org-heading-regexp-build (s)
  (let* ((sp (reverse (org-split-string s)))
         (wspace "[ \t]")
         (wspaceopt (concat wspace "*"))
         (cookie (concat "\\(?:"
                         wspaceopt
                         "\\(?:\\[[0-9]+%\\]\\|\\[[0-9]+/[0-9]+\\]\\)"
                         wspaceopt
                         "\\)"))
         (sep (concat "\\(?:" wspace "+\\|" cookie "+\\)"))
         res)
    (dolist (w sp) (setq res (concat w sep res)))
    (concat sep res)))
#+end_src

This of course needs to be extended with the other headline features
(todo keyword, tags, …), this is just to know if I'm on the right track.

Best,

Alan
