Org ASCII export with indentation preserved

Question

Open your EMACS -Q, enter org mode, and

#+begin_src emacs-lisp

  (setf x '(a b c
              d e f))

#+end_src             

This is how it will be aligned after org-edit-special (C-c ').

Now export to an ASCII buffer with C-c C-e t A. You will see

,----
| 
| (setf x '(a b c
|           d e f))
| 
`----

Clearly, the indentation has changed. How does one get indentation as in the source?

P.S.

This does not happen when exporting to a LaTeX buffer. It seems to be a bug resulting from the use of tab characters and the insertion of two extra characters at the beginning of each source line. I suppose plain-text export isn't used that much.

Just see to it that the whole buffer is free of tabulators before you export it. To avoid untabbing the original, use a hook.

    (defun org*-export-untabify (backend)
      (untabify 0 (point-max)))

    (add-hook 'org-export-before-parsing-hook 'org*-export-untabify)
