fenced_code_attributes: documentation or code is wrong...

[docwhat]

The documentation for fenced_code_attributes says:

If the fenced_code_attributes extension is disabled, but input contains class attribute(s) for the codeblock, the first class attribute will be printed after the opening fence as a bare word.

However, when given this input:

~~~ sh
echo 'hi'
~~~

And running with pandoc --to=markdown-fenced_code_attributes I get this output:

~~~~
echo 'hi'
~~~~

I expected to get this instead:

~~~~ sh
echo 'hi'
~~~~

If I run this command pandoc --to=markdown-fenced_code_blocks I get something closer to what I expect:

``` sh
echo 'hi'

It leads me to believe either I don't understand `fenced_code_blocks` and `fenced_code_attributes`.

What does pandoc --version say? The documentation reflects the latest version 1.13.0.1.

[docwhat]

It's 1.13.0.1 from Homebrew.

Here's what I'm seeing with 1.13.0.1:

% pandoc --to=markdown-fenced_code_attributes
~~~ sh
echo 'hi'
~~~
^D
``` sh
echo 'hi'
```

So I can't reproduce what you're seeing. Are you sure you were running 1.13.0.1 and not an older version on your system? Did you use other options that might be interfering?

[mpickering]

Can't reproduce this issue either.
