Highlight the code between the 3 backticks

[parmi93]

First of all, great extension, deserves much more attention.

The inline code colorization between backticks (` `) is fantastic; it really enhances the readability of the comments.

Would it be possible to have the same kind of colorization for the triple backticks?

/**
 * @brief Foo description
 *
 * Example call:
 * ```c
 * foo();
 * ```
 */
void foo();

I surely would like to implement this. The problem ist that it is non-trivial. Currently, the parser always considers only individual lines. Your case requires information about multiple lines. There is also the issue that the * before foo() should still appear without special formatting.
I did this originally for simplicity and never improved it since then.

I do plan on improving the extension in the future, but no promises when it will happen.
