Hi Nicolas,
This patch looks great! Thanks for the contribution. However before I
apply this patch, can I ask, have you signed the FSF papers.
As org-babel is being incorporated into the core of Org-mode and will be
considered part of Emacs we need authors of any contributions longer
than 10 lines to sign the FSF papers.

Thanks -- Eric
