Hi all,

I just pulled a fresh version of org, and this tangling an individual
block only works if there's a :tangle header argument present.  I
don't think this is the intended behavior!  The problem, it seems, is
that when :tangle is not present, the (or ...) in the code below
always evaluates to true.

#+begin_src emacs-lisp
      (unless (or (cdr (assoc :tangle (nth 2 (org-babel-get-src-block-info))))
        (setq target-file
              (read-from-minibuffer "Tangle to: " (buffer-file-name)))))
