Re: org-detangle seems broken

Hi Nicolas,

Here it is. If you =detangle= the =broken-detangle--working.el= file, it
will work as expected.

However, if you try to detangle the =broken-detangle--NOT-working.el= file,
you should get a "Not in a source block" error in *message*.

Another thing I noted while creating the ECM is if there is only *one* code
block in the =.org= file, then it throws a =End of Buffer= error.

* Experience broken detangle

In this example, if we tangle this file and immediately detangle it, everything is working as expected without error messages from Org.

#+BEGIN_SRC elisp :tangle broken-detangle.el :comments link
(defun test
    (message "broken detangle"))
#+END_SRC

If I update the *source* file with the following code and that I detangle it, it works as expected:

#+BEGIN_SRC elisp :tangle broken-detangle.el :comments link
(defun test
    (message "broken detangle")
  (message "test"))
#+END_SRC

However, if I add a line of code like this, then I am currently getting a =Not in a source block".

#+BEGIN_SRC elisp :tangle broken-detangle.el :comments link
(defun test
    (message "broken detangle")
    (message "test")
    (message "test"))
#+END_SRC

Another thing to note, if there is only *one* code block in the Orgmode file, then I am getting a =End of Buffer= instead.
