[O] Make Org-Babel keyword lowercase

[Thorsten Jolitz]

Hi List, 

I have this in my init-file:

,-------------------------------------------
| ;; Make babel results blocks lowercase
| (setq org-babel-results-keyword "results")
`-------------------------------------------

and would like to insert _all_ babel block-keywords in lowercase
(#+begin_src instead of #+BEGIN_SRC etc.), and I even remember that I
had this configuration in the past, but I can't find the related
customizations anymore.

Any hints?
