Wow, thanks a lot Kylie, this was it! I never thought of having to unfold the Org mode entries in a buffer when opening in a non interactive way.

I do this now from a lisp buffer and both functions work exactly as expected:

single file:
============

(let ((fill-column most-positive-fixnum))
  (dolist (f (list "~/lorem.org"))
    (with-current-buffer (find-file-noselect f)
      (org-show-all)
      (while (not (eobp))
        ;; (mark-whole-buffer)
        (fill-paragraph)
        (org-forward-paragraph))
      (save-buffer))))


recursively through dir tree:
=============================

(let ((fill-column most-positive-fixnum))
  (dolist (f (directory-files-recursively
              "/dirs/with/org/files/" (rx (or ".org" ".outl") eos)))
    (with-current-buffer (find-file-noselect f)
      (org-show-all)
      (while (not (eobp))
        (fill-paragraph)
        (org-forward-paragraph))
      (save-buffer))))


That's great; I'm glad it works now from within emacs itself (and not via sed, awk or tr as I tried before), harnessing all the knowledge the editor has of its own constructs, especially with some of the more complicated list and enumeration structures, -- all of them are correctly unfilled now.

Thanks again

Gerald.
