Support for source code environment in AsciiDoc output

[manuelfuenmayor]

verbatim and listingsenvironments are usually used for typesetting source code in LaTeX, and it seems we don't have support for them yet. For example,

Verbatim source code in LaTeX:

\begin{verbatim}
class HelloWorldApp {
  public static void main(String[] args) {
    //Display the string
    System.out.println("Hello World!");
  }
}
\end{verbatim}

results in:

class HelloWorldApp {
  public static void main(String[] args) {
    //Display the string
    System.out.println("Hello World!");
  }
}

Though the expected result should be like:

----
class HelloWorldApp {
  public static void main(String[] args) {
    //Display the string
    System.out.println("Hello World!");
  }
}
----

And, in regard to listings environment. (Maybe this one is more complicated to handle.)

Listings source code in LaTeX:

\begin{lstlisting}[language=java]
class HelloWorldApp {
  public static void main(String[] args) {
    //Display the string
    System.out.println("Hello World!");
  }
}
\end{lstlisting}

results in

**class** HelloWorldApp {  **public** **static** **void** main(String[] args) {    __//Display the string__    System.out.println(”Hello␣World!”);  }}

And the expected result (if possible):

[source,java]
----
class HelloWorldApp {
  public static void main(String[] args) {
    //Display the string
    System.out.println("Hello World!");
  }
}
----
