Hello,
Following a thread started by Samuel Wales (see
http://permalink.gmane.org/gmane.emacs.orgmode/66558), it appears that
the standard way to include multiple paragraphs in a footnote definition
is to rely on "\par" LaTeXism.
There are two problems here. Firstly, the parser would have to go out of
its way to support this trick. Secondly, it isn't very regular wrt Org
syntax.
I suggest to end a footnote definition at a headline, another footnote
definition or *two* blank lines.
Pros:
- Small modification to code base.
- More regular syntax (lists use the same)
Cons:
- Still impossible to have two consecutive lists (because they need
to be separated by 2 blank lines).
- Small incompatibility with previous syntax.
Is there any objection to apply this patch?
Regards,

Subject: [PATCH] Require 2 blank lines to separate footnote definition
* lisp/org-element.el (org-element-footnote-definition-parser):
Require 2 blank lines to separate footnote definition.
* lisp/org-footnote.el (org-footnote-at-definition-p): Require 2 blank
lines to separate footnote definition.
Footnote definitions can still be separated with other footnote
definitions and headlines. This change allows to have multiple
paragraphs in a footnote definition.

Nicolas,
I don’t know how difficult this would be in terms of the code, but would
it be possible to introduce a new syntax for multiparagraph footnotes?
Something like:
#+begin_footnote 12
This is footnote number 12.
etc.
#+end_footnote
This has the advantage that long footnote definitions could be folded,
which (AFAIK) they currently cannot. And it would not have the problem
with multiple lists.
Just a suggestion,

They cannot be folded, but they can be collected in a specific headline,
which can be folded.

Consecutive lists limitation is anecdotal, really. Also, this syntax
would break every footnote definition, unless you mean to add syntax
only for multiparagraph footnotes. But I think we don't have to go that
far.
My proposal doesn't really introduce some new syntax. It merely
normalizes a corner-case.

Thank you for asking the list.
Does this allow blank lines to separate paragraphs in inline footnote
definitions?
If so, it sounds very good.
I presume we can still do
===
1) a
b.
1) c
===

No. Inline definitions stay inlined and as such, cannot contain blank
lines. My proposal is only about full footnote definitions.

Yes, the limitation is only about two consecutive lists. In this case,
they are not consecutive.

Patch applied.
As a reminder, it only requires some change if:
1. you used "\par" in the footnote definition: now you can replace it
with a single blank line.
2. you need regular text (i.e. not a headline or another footnote
definition) after the definition: separate definition and text with
two empty lines.
