Hi,

Moving from an emacs with an old org-mode (6.33) to the latest stable one
currently (8.3.2), I noticed two changes which made me out of my comfort
area.

   1. Demoting/promoting a header now changes the indentation of text below.
   I reverted to the previous mode with '(setf org-adapt-indentation nil)'
   in ~/.emacs, and that's fine but I mentioned it in case it has an impact on
   point#2.

   2. 'M-x fill-region' does not fill custom lists as before. In the
   previous version, I could select and fill several mixed paragraphs/lists
   directly. For example, filling the following block (without --- separator
   added as a delimiter in this message)
   ---------------
   # a very looooooooooooooooooooooooooooooooooooooooooooooooooooong comment

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence that
   should be filled over 2 lines

   - a looooooooooooooooooooooooooooooooooong item that should be filled
   over 2 lines

     - a looooooooooooooooooooooooooooooooooong item that should be filled
   over 2 lines

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence that
   should be filled over 2 lines
   ---------------
   resulted in (version 6.33):
   ---------------
   # a very looooooooooooooooooooooooooooooooooooooooooooooooooooong comment

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence
   that should be filled over 2 lines

   - a looooooooooooooooooooooooooooooooooong item that should be filled
     over 2 lines

     - a looooooooooooooooooooooooooooooooooong item that should be
       filled over 2 lines

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence
   that should be filled over 2 lines
   ---------------
   and now results in (version 8.3.2):
   ---------------
   # a very looooooooooooooooooooooooooooooooooooooooooooooooooooong comment

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence
   that should be filled over 2 lines

   - a looooooooooooooooooooooooooooooooooong item that should be filled
   over 2 lines

     - a looooooooooooooooooooooooooooooooooong item that should be filled
   over 2 lines

   a looooooooooooooooooooooooooooooooooooooooooooooooooooong sentence
   that should be filled over 2 lines
   ---------------

   Lists are not filled anymore and I have to select each list entry and
   fill it individually to get the same output.

So my questions are:

   - Is there any simple way to revert to the previous mode with a variable?
   - Else, could you explain briefly where I should look if I want to
   understand why the filling is skipped in this case, and eventually change
   it if I cannot change my mind and adapt to this different behavior? I had a
   look at function (org.el:23249 org-setup-filling) but I am not sure this is
   the right location.

Thanks, and have a nice day.
