Make inline code distinguishable from code blocks

[thekid]

Input

Inline `code`!

```
Block of code
```

Output

<p>Inline <code>code</code>!</p>
<code>Block of code
</code>

Problem

We want to highlight the code block, but don't want to do that for inline code. However, in the outputted HTML, they are not distinguishable.

Idea

Wrap the <code> inside <pre>. This would (by default):

• Remove the necessity of styling the code element with white-space: pre-wrap
• Make it easily interoperable with https://highlightjs.org/
• Make it compliant with Marked.JS for example

Implementation is easy:

diff --git a/src/main/php/net/daringfireball/markdown/ToHtml.class.php b/src/main/php/net/daringfireball/markdown/ToHtml.class.php

However, it breaks BC, so we would have to go for a major release.
