Fenced Code Block Identifiers not working for Latex or PDF output

[Vinai]

I'm trying to link to identifiers for fenced code blocks. The input is pandoc markdown, output is a PDF file. The code block identifiers are not being created.

Test markdown to reproduce:

## Fenced Code
## Header with explicit identifier {#myhead}

~~~ {#php-code .php}
class Customergroup extends Data_Form_Element_Multiselect
{
    /**
     * @return int
     */
    public function getValue()
    {
        $value = $this->getData('value');
        if (!is_null($value) && !is_array($value)) {
            $value = explode(',', (string)$value);
        }
        if (empty($value)) {
            $value = array(Config::USE_DEFAULT);
        }

        return $value;
    }
}
\~~~

This is a link to the [PHP](#php-code). <== doesn't work  
This is a link to the [header](#fenced-php-code). <== works  
This is a link to the [sub-head](#myhead). <== works  

Please note, I had to break the closing ~~~ by prefixing a backslash, otherwise the github markdown parser would render the next 3 lines as plain html instead of as part of the code block. In the real markdown I'm using that \ is not present.

Here a link to the answer from fiddlosopher for my question on pandoc-discuss as reference:

https://groups.google.com/d/msg/pandoc-discuss/6_XWo3mkQOU/LYxYWOop_KAJ

I quote:

The ID attribute is set in HTML output.

Currently it doesn't do anything in LaTeX output. That could be changed -- presumably a hyperlink anchor could be set as with headers.

If you compile with the --listings option it should be working (see #961 ). But without you're right. That is currently not working.
