Thanks for the quick reply!  Fwiw, I agree about the drawbacks of  
visual-line-mode, but somewhat to my surprise I found that I like it  
in text modes, so I turn it on conditionally in text-mode-hook.

On the other hand, I use org-special-ctrl-a/e as well.  So I hacked in  
treatment of line-move-visual at the beginnings of org-{beginning|end}- 
of-line (sorry no unified diff, just pasted the function beginnings):

(defun org-beginning-of-line (&optional arg)
   "Go to the beginning of the current line.  If that is invisible,  
continue
to a visible line beginning.  This makes the function of C-a more  
intuitive.
If this is a headline, and `org-special-ctrl-a/e' is set, ignore tags  
on the
first attempt, and only move to after the tags when the cursor is  
already
beyond the end of the headline."
   (interactive "P")
   (let ((pos (point)) refpos)
     (if line-move-visual
         (beginning-of-visual-line 1)
         (beginning-of-line 1))
     (if (and arg (fboundp 'move-beginning-of-line))
[...]

and

(defun org-end-of-line (&optional arg)
   "Go to the end of the line.
If this is a headline, and `org-special-ctrl-a/e' is set, ignore tags  
on the
first attempt, and only move to after the tags when the cursor is  
already
beyond the end of the headline."
   (interactive "P")
   (if (or (not org-special-ctrl-a/e)
           (not (org-on-heading-p))
           arg)
       (call-interactively (cond (line-move-visual 'end-of-visual-line)
                                 ((fboundp 'move-end-of-line) 'move- 
end-of-line)
                                 (t 'end-of-line)))
     (let ((pos (point)))
       (beginning-of-line 1)
[...]

For emacsen <23, the check for line-move-visual should use boundp or  
bound-and-true-p, of course.

I believe these changes count as trivial w.r.t. copyright assignment,  
should you decide to merge them (which I'd be happy if you did, of  
course :) ).

Greetings,

Rudi
