Hi

Following a recent discussion (based on me forgetting a ":" when setting
the property :header-args), I added the output of the property
header-args to the output of org-babel-get-src-block-info to make
debugging easier. Before the function resulted in the following output
(using my faulty code block):

,----
| Lang: R
| Header Arguments:
| 	:cache		no
| 	:exports	both
| 	:hlines		no
| 	:noweb		no
| 	:results	code exports output replace
| 	:session	somename
| 	:tangle		no
| 
`----

One only saw that the property :results was not correct but not where it
came from.

Using the patched version, one gets the following:

,----
| Lang: R
| Properties:
| 	:header-args 	:exports both :results output exports code
| 	:header-args:R 	:session somename
| Header Arguments:
| 	:cache		no
| 	:exports	both
| 	:hlines		no
| 	:noweb		no
| 	:results	code exports output replace
| 	:session	somename
| 	:tangle		no
`----

Here one can clearly see that the property :header-args is not set
correctly and can easily trace it down in the original org file.

Also, actually seeing the property :header-args makes it easier to
understand the whole inheritance of header arguments and how header-args
and header-args+ interact. 

The same applir=es to the property :header-args:R (or any language
specific header-args:language property)

Cheers,

Rainer


Here is again the faulty org file which lead to the patch:

--8<---------------cut here---------------start------------->8---
#+PROPERTY: header-args:R :session somename
#+PROPERTY: header-args :exports both
#+PROPERTY: header-args+ :results output
* The bug
This file create an (possibly endless?) loop during export
* here exports both
#+begin_src R 
cat(13+14)
#+end_src

* and here only code
:PROPERTIES:
:header-args+: exports code
:END:
#+begin_src R 
paste(13+14)
#+end_src
--8<---------------cut here---------------end--------------->8---
