[O] Problem jumping back & forth between foonote ref and def with 'C-c C-c'

[Alain . Cochard]

Hello.  

I start emacs with

   emacs -Q -l .emacs.debug

where the file .emacs.debug contains only

   (add-to-list 'load-path "/home/cochard/Org/Coch-git/org-mode/lisp")

giving

   Emacs : GNU Emacs 24.5.1 (x86_64-redhat-linux-gnu, GTK+ Version
   3.18.9) of 2016-04-11 on buildvm-25.phx2.fedoraproject.org Package:
   Org mode version 9.1.13 (release_9.1.13-894-gf79545 @
   /home/cochard/Org/Coch-git/org-mode/lisp/)

The manual says:

   ‘C-c C-c’
   If the cursor is on a footnote reference, jump to the definition.
   If it is a the definition, jump back to the reference.  

Now, I visit a file which contains only

   * head
   foo[fn:1] bar
   * Footnotes

   [fn:1] tnote

If the cursor is anywhere within the 1st instance of '[fn:1] ' (that
is, including the space) and I type 'C-c C-c' the cursor ends up on
the 1st letter of 'tnote'.

I am not sure if this corresponds to what the manual says but, if I
type 'C-c C-c' again, I get

   user-error: `C-c C-c' can do nothing useful here

i.e., I don't "jump back."  By contrast, with

   emacs -Q

which gives

   Emacs : GNU Emacs 24.5.1 (x86_64-redhat-linux-gnu, GTK+ Version
   3.18.9) of 2016-04-11 on buildvm-25.phx2.fedoraproject.org Package:
   Org-mode version 8.2.10 (release_8.2.10 @
   /usr/share/emacs/24.5/lisp/org/)

if the cursor is anywhere within the 1st instance of '[fn:1]' and I
type 'C-c C-c' the cursor ends up on the space before 'tnote'.  A 2nd
'C-c C-c' brings the cursor back to the 1st '[' of the 1st '[fn:1]'.
This does correspond to what I would qualify as "jumping back."

In other words, version 8.2.10 behaves as I expect, not the master
version.  Am I doing/understanding something wrong?

Thank you,
regards.

PS: note the typo in the manual excerpt: "If it is a the
definition...".
