[Orgmode] Sorting and renumbering footnotes

[Karl Maihofer]

I use Org to write quite long documents with many footnotes and I am  
wondering if there is a way to renumber the footnotes when sorting  
with "C-u C-c C-x f s". "n" at the end is not what I am looking for.  
I'd like the footnotes to stay at the position set by  
org-footnote-section.

Simple visual example:

-------------------------------------------
* First Headline

Org-mode is for keeping[fn:2] notes, maintaining ToDo lists, doing  
project[fn:3] planning, and
authoring with a fast and effective[fn:1] plain-text system.

[fn:1] Third Footnote.

[fn:2] Frist Footnote.

[fn:3] Second Footnote.

* Second Headline
---------------------------------------------

Pressing "C-u C-c C-x f s" resuls in the following:

----------------------------------------------
* First Headline

Org-mode is for keeping[fn:2] notes, maintaining ToDo lists, doing  
project[fn:3] planning, and
authoring with a fast and effective[fn:1] plain-text system.

[fn:2] Frist Footnote.

[fn:3] Second Footnote.

[fn:1] Third Footnote.

* Second Headline
-----------------------------------------------

How can I achieve this:

-----------------------------------------------
* First Headline

Org-mode is for keeping[fn:1] notes, maintaining ToDo lists, doing  
project[fn:2] planning, and
authoring with a fast and effective[fn:3] plain-text system.

[fn:1] Frist Footnote.

[fn:2] Second Footnote.

[fn:3] Third Footnote.

* Second Headline
