[O] [bug] [babel] repeated exports w/ inline src blocks yield different results

[Charles Berry]

Consider this code:

,----
| * test
| 
| #+NAME: block2
| #+BEGIN_SRC emacs-lisp :exports both
|     (setf not-yet-bound-a t )
| #+END_SRC
| 
| src_emacs-lisp{(+ 1 1)}
| 
| end of buffer
| 
`----
 
Upon export via 

 C-c C-e C-b t A y y 

 yields:
,----
| 1 test
| ======
| 
|   ,----
|   | (setf not-yet-bound-a t )
|   `----
| 
|   ,----
|   | t
|   `----
| 
|   `2'
| 
|   end of buffer
| 
`----

just as one would hope.

But trying it again, 

 C-c C-e C-b t A y y 

gives
,----
| 1 test
| ======
| 
|   ,----
|   | (setf not-yet-bound-a t )
|   `----
|   #+END_SRC
| 
|   ,----
|   | t
|   `----
| 
|   `2'
| 
|   end of buffer
| 
`----

and you see the extra '#+END_SRC' line.

And if you keep repeating those keystrokes, the second result again appears.

However, sometimes a minor change and then an erasure (perhaps 'a a C-x u')
followed by the export keystrokes yields the correct result.

There are some other forms of misbehavior: if  I change the header arg
in the src block to  ":exports results", then the first export is correct,
but the second export skips execution of the src block and writes the code
in the export as if ':exports code' had been given. 

But again 'a a C-x u' seems to clear whatever condition causes the 
misbehavior.

Remove the "src_emacs-lisp{...}" and clear with 'a a C-x u' and
everything works fine again through multiple exports. I tagged the 
subject line '[babel]' because of that.
