Subject: Unwanted "(progn )" when Tangling Lisp Code
Date: Tue, 31 May 2011 11:39:38 +1000	[thread overview]
Message-ID: <BANLkTikGB2UGRD__jmgV9OqzuKQCOasKfA@mail.gmail.com> (raw)


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))
: (progn (defun mischief ()
:   (/ 1 0))
: )

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


Here is the patch.
