[O] org-copy-visible does not work with x-select-enable-primary

[Alain . Cochard]

Hello.


I use

   emacs -Q -l ~/.emacs.debug

with the ~/.emacs.debug file containing only

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

I tried 2 versions of emacs, 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 9.1.14 (release_9.1.14-908-gf1269e @
   /home/cochard/Org/Coch-git/org-mode/lisp/)

   Emacs : GNU Emacs 26.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version
   3.18.9) of 2018-05-30 Package: Org mode version 9.1.14
   (release_9.1.14-908-gf1269e @
   /home/cochard/Org/Coch-git/org-mode/lisp/)

In both cases, org-copy-visible works as I expect: if I select region
containing a folded tree, use 'M-x org-copy-visible', then put the
cursor elsewhere and use 'M-x org-yank', only the visible part is
copied.

Now, if I append the line

   (setq x-select-enable-primary t) 

to ~/.emacs.debug, the whole tree is copied instead of the expected
result, that is, including the invisible parts, also for the two emacs
versions.

NB: For emacs 26, as the manual says that 

   [x-select-enable-primary] is an alias for ‘select-enable-primary’.
   This variable is obsolete since 25.1; use ‘select-enable-primary’
   instead.

I have also tried (setq select-enable-primary t) but this fails in the
same way.

Regards
