Re: [Orgmode] Footnotes and org-export, revisited

[Carsten Dominik]

Hi Matt, thanks for this much needed feedback.  I was already working
into the direction of some of your proposals, but certainly not all.

Yes, this would be much more consistent.  Now it does this,
sorting will move each definition to the entry of the first
reference, if org-footnote-section is nil.

Done.

I agree that this would be nice, but multiline font-lock (which
would be needed to do this) is relatively fragile.  I believe John & CO
have a better font-lock scheme in muse wich does handle this stuff  
better,
but I would need time to study how tis exactly works.

So no for now.

Yes.  Footnote export to LaTeX is actually silly.  It first extracts
all notes to the end of te buffer during preprocessing, and then
moves them back during export :-)

Isn't the new sorting good enough for this?  I am uncomfortable with
letting a program doing so much complex editing.  I think it will
break too often.

This option does now exist:

org-footnote-fill-after-inline-note-extraction

The only problem s that while Org-s fill-paragraph does the right
thing under most circumstances, there are cases where it is imperfect
or even breaks things.  Try it, mostly it should work.
In fact, this is relevant only for normalizing in the buffer, and for  
the
ASCII backend.  The other backends do not care.

Thanks, please keep testing and the feedback coming.
