Re: Indentation of code blocks within lists

["Sebastien Vauban" <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello Francesco,

That won't help you, but I've already sent questions on this problem, last
year (Org < 8). See my post on
http://lists.gnu.org/archive/html/emacs-orgmode/2012-02/msg00247.html.

Though, it's (for me) still unfixed as of today.

The good news is that Nicolas seemed OK to look at it, and find a solution for
it...

Best regards,
  Seb
