Eu resolvi esse problema modificando org/lisp/org-footnote.el
- Comente uma linha na definição de "org-footnote-re"
(defconst org-footnote-re
;; Only [1]-like footnotes are closed in this regexp, as footnotes
;; from other types might contain square brackets (i.e. links) in
;; their definition.
;;
;; 'org-re' is used for regexp compatibility with XEmacs.
(concat "\[\(?:"
;; Match inline footnotes.
(org-re "fn:\([-_[:word:]]+\)?:\|")
;; Match other footnotes.
"\(?:\([0-9]+\)\]\)\|" ; <-------- comment out this line
(org-re "\(fn:[-_[:word:]]+\)")
"\)")
"Regular expression for matching footnotes.")
- Altere o argumento da função 'org-re' aqui.
(defconst org-footnote-definition-re
(org-re "^\[\([0-9]+\|fn:[-_[:word:]]+\)\]")
"Regular expression matching the definition of a footnote.")
Alterar cadeia
"^\[\([0-9]+\|fn:[-_[:word:]]+\)\]"
para
"^\[\(fn:[-_[:word:]]+\)\]"
