I have file with a large number of SRC blocks, the output of which I
want to wrap as SRC (so I can use the listings package to format them
distinctly). The easiest way to do this is to make :wrap a global
property. Unfortunately, there are also a couple of places where I want
to turn off the wrapping, especially where I include source in-line. 
For example, this:

    #+PROPERTY: wrap SRC fundamental

    #+BEGIN_SRC emacs-lisp
    "This output comes from emacs."

    This in-line src_emacs-lisp[:results value]{"block"} is wrapped.

    | "This output comes from emacs."

    This in-line #+BEGIN_SRC fundamental block#+END_SRC is wrapped.

If I pass an empty :wrap in the in-line block, the result is still
wrapped, but as RESULTS instead of source.

The attached patch attempts to change this behaviour. Does anyone else
find this desirable? Is this patch a good way to do it?

Kind Regards,
