Bug: \vert{} exported to markdown not as expected [8.3.1 (8.3.1-103-g366dc4-elpa @ /home/bitouze/.emacs.d/elpa/org-20150907/)]

[dbitouze@wanadoo.fr (Denis Bitouzé)]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

The following file:

#+NAME: test.org
#+begin_src org
Foo |bar_baz|

Foo \vert{}bar\under{}baz\vert{}
#+end_src

is exported to markdown as follows:

#+NAME: test.md
#+begin_src markdown
Foo |bar\_baz|

Foo |bar_baz|
#+end_src

Whereas:

- \under{} gives the expected underscore symbol (_),
- \vert{} gives | instead of the expected pipe symbol (|).
