Hi!

I've an issue with radio targets and ordinary external links.

#+begin_src org
#+ATTR_HTML: border="1" frame="border" style="max-width:50%;"
| / | <>           | <>             | <>                           |
|   | Test         | Description    | Source  file                 |
|---+--------------+----------------+------------------------------|
|   | <<<IDCT>>>   | Inverse DCT    | [[file:test/idct.c][idct.c]] |
|---+--------------+----------------+------------------------------|
#+end_src

In this case external link "[[file:test/idct.c][idct.c]]" in html file
looks like: <a href="test/idct.c">.c</a>

I confirm the bug, not only with the HTML exporter, but with the LaTeX
exporter -- and probably all of them.

For HTMl, the description of the second link is already wrong when
`org-html-link' uses it as an argument.  Probably something strange
when setting the radio targets that prevents the link desc to be
parsed correctly.

I'll let Nicolas have a look when he has time.

Thanks,

Indeed. This was a two-part bug. I fixed the first one, but the second
one is non-trivial and yet to be fixed.

The problem is that "idct" in the link description is recognized as
a reference to the radio target <<<IDCT>>>.

In a perfect world, links wouldn't be allowed within link description,
and the problem wouldn't exist, but there's also the following construct
in Org:

  [[http://orgmode.org][file:./unicorn.jpg]]

Obviously, the contents of the link is a link, and, in this case it even
makes sense. That's why links are allowed within links (and therefore
links to radio targets).

This is a limitation from Org syntax: it has no proper way to define an
"image" so it relies on links to display them. If there was an "image"
type object, I could easily allow images within links, but not links
themselves.

Anyway, I'll try to find a workaround.
