Feature request: setq org-agenda-follow-indirect 'parent

[Nicolas Girard <girard.nicolas@gmail.com>]

Hi all,

when browsing my TODO items in the agenda, I wish I could display then
in an indirect buffer.
But as I structure my stuff, displaying the tree with a TODO item as
root is often useless.

Indeed, within my PROJECT items, I differentiate between TODO and
support (notes, references) children ; for instance
#+BEGIN_SRC org
  ,* PROJECT My project
  ,** References
  ,*** Ref 1
  ,*** Ref 2
  ,** Notes
  ,*** Note 1
  ,*** Note 2
  ,** TODO Todo item 1
  ,** TODO Todo item 2
#+END_SRC

In this example, in order to work on, or even decide anything about
"Todo item 1", chances are that I'd also need to see the contents of
the "References" and "Notes" items ; so the tree I'd need to see in
the indirect buffer should have the *parent* of "Todo item 1" as root,
instead of "Todo item 1" itself.

It seems rather easy to achieve, since `org-agenda-do-context-action'
calls `org-agenda-tree-to-indirect-buffer', which is supposed to deal
with this case when called with a numerical prefix argument ; so I did
give it a try but couldn't get it to work properly :-(

Cheers,
Nicolas
