[O] Unwanted "(progn )" when Tangling Lisp Code

[Mark Cox]

Hi,

When tangling lisp source code blocks, the tangled code is wrapped in
a `(progn ,@body). For example,
the block
#+begin_src lisp :tangle example.lisp
(defun mischief ()
  (/ 1 0))
#+end_src
produces
: (progn (defun mischief ()
:   (/ 1 0))
: )

With the attached patch, the tangling process now produces
:
: (defun mischief ()
:   (/ 1 0))

Thanks
Mark

Here is the patch.
