Hi all,
This patch fixes a bug where the regexp for parsing source blocks is too
greedy on the body and so fails in the presence of empty code blocks. For
instance given the following:

#+begin_src c
#+end_src

#+begin_src c
hello world
#+end_src

, doing (org-babel-get-src-block-info) the first #+begin_src will include
everything up to the second #+end_src as part of the body.
