add extra tag to block code @
fix double encoding in code

add the possibility to do:
@(php).

if tags in the textile string is already encoded it will be reencoded in
code block:
@
<div> oo </div>
@
become:
<div > oo </div >

this change avoid double encoding

Downfall is that the encoding change prevents you displaying entities in code blocks, or anywhere. Any included pattern matching an entity in a string, will pass through and is processed by the browser. This causes a mixing of different encoding iteration levels in different parts of the code block which is not ideal. Whether the string is pre-encoded or not, you would have pre-encode (or double encode) any pattern matching an entity. This encoding change isn't limited to code block only. The Parser::encodeHTML() is the sanitizer in Textile.

The expectation that I personally have is that when someone is using Textile, they are using it to format any provided content, allowing you to type in just plain text without worrying about anything else. The content can contain mix of HTML, but Textile takes care of the important stuff as proper sanitation, encoding and security. For instance if you provide HTML to bc tag, the expectation would be that it encodes that string no matter what it contains.

More commits the merrier. The less distinct changes a single commit or a pull request contains the better ;-)

Oh yeah, having attributes in inline code tags would be definitely good. You will not normally need it as much as code blocks due to semantic validity, but when you do, being able to state the used language via a class would definitely be beneficial. Even for syntax highlighting if not anything else.
