Bug: Link descriptions in org-element parser

Bug: Link descriptions in org-element parser

When having an link where the link's description also look like a link,
the description will be treated like a link by org-element. As an
example:

    [[info:emacs#Directory%20Variables][info:Directory Variables]]

If the above was an org-file, org-element-parse-buffer would find two
links in the buffer, but the above is really just one link even though
its description look like a link. A consequence of this is that the
org-element-contents of the link above would be another link, which can
cause bugs.

I'm using org-mode 9.0.5 on Emacs 25.2.1.

IIRC, this was fixed a while ago. You may want to update Org.

Hi!

I've updated to org-mode 9.0.7 but the problem remains. With this org-mode
buffer

    [[info:emacs#Directory%20variables][info:Directory variables]]

org-element-parse-buffer give the following (indented):

(org-data
 nil
 (section
  (:begin 1 :end 92 :contents-begin 1 :contents-end 92 :post-blank 0
:post-affiliated 1 :parent #0)
  (paragraph
   (:begin 1 :end 65 :contents-begin 1 :contents-end 64 :post-blank 1
:post-affiliated 1 :parent #1)
   (link
    (:type info :path emacs#Directory%20variables :format bracket :raw-link
info:emacs#Directory%20variables :application nil :search-option nil :begin
1 :end 63 :contents-begin 37 :contents-end 61 :post-blank 0 :parent #2)
    (link (:type info :path Directory :format plain :raw-link
info:Directory :application nil :search-option nil :begin 37 :end 52
:contents-begin nil :contents-end nil :post-blank 1 :parent #3))
    variables))))

So the org-element-contents of the link is another link.

Then it was probably fixed in master branch, i.e., development version.
At least I cannot reproduce it. The fix will be included in Org 9.1.
