Bug: Incorrect result of exporting info link [9.0.1 (release_9.0.1-143-g469103 @ /home/xcy/src/org-mode/lisp/)]

Hi org-mode list.

At (info "(emacs) Echo Area"), 'M-x org-store-link' stores the link as:

[[info:emacs#Echo%20Area][info:emacs#Echo Area]]

however org doesn't export it correctly, for example, the result of html
export is:

<a href="http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Echo-Area"><a href="http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Echo">emacs#Echo</a> Area</a>

the correct result should be:

<a href="http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Echo-Area">emacs#Echo Area</a

and the result of ASCII export is:

[[info:emacs#Echo] Area]
[[info:emacs#Echo] Area] info:emacs#Echo%20Area

the correct result should be:

[info:emacs#Echo Area]
[info:emacs#Echo Area] info:emacs#Echo%20Area

I tried to debug this by inserting

(message "-> org-info-export: path: [%s] desc: [%s]" path desc)

at the beginning of org-info-export, then export, it shows

-> org-info-export: path: [emacs#Echo] desc: [nil]
-> org-info-export: path: [emacs#Echo Area] desc: [[info:emacs#Echo] Area] [2 times]

It looks like one info link is exported three times.


\f
BTW, I'm relative new to org-mode and the mailing list. I have some
questions: 1) does org-mode have a bug track system? Before reporting a
bug, I would like to make sure it's not already reported. 2) I notice
that subjects of mails in the mailing list are all prefixed with "[O]",
I guess it is for filtering. My question is: do I need to add "[O]" at
the beginning of my subject manually? or is it added automatically?

Thanks for your help.

It's not really a bug in the exporter, but rather a poor parser design
decision. Basically "info:emacs#Echo" is a valid link in Org, even as
a description of another link.

I removed nested links in parser. Instead I added a tool in "ox.el",
namely `org-export-insert-image-links' to add them whenever a back-end
can make use of them.

I made that change in master. So, the issue should be fixed there.

Thank you.
