Aloha all,

The attached patch defines a new header argument, :special, which wraps
the results of Org babel source block execution in a #BEGIN_ ... #+END_
block.  The block name is taken from a new variable
org-babel-wrap-special, which is initialized as "results".

I use this in conjunction with org-special-blocks for LaTeX export.  I'm
writing a didactic article where I set off results and format them with
the LaTeX framed package. 

All the best,
Tom
