[O] Bug: ob-ditaa fails in generating pdf correctly

[Anders Johansson]

Hi,
Example input:
#+header: :eps t
#+header: :file hello.pdf
#+BEGIN_SRC ditaa
+--------------+
|              |
|    Hello     |
|              |
+--------------+
#+END_SRC


When using the above code (which I guessed should be the correct way) 
with ob-ditaa to produce a pdf (through  DitaaEps -> epstopdf) it fails 
in producing the pdf correctly and instead writes an eps to "hello.pdf". 
This isn't surprising, looking at the code where "cmd" should be 
constructed to produce the eps as an intermediary file in /tmp (which is 
expected in the construction of pdf-cmd) but doesn't.

An ugly patch to fix it is attached (this is ugly because it repeats the 
line:
(org-babel-process-file-name (concat in-file ".eps"))
)

Cheers,
Anders Johansson
