Ruby class variables aren't fully highlighted

[GoogleCodeExporter]

1. Specify a ruby class variable, e.g. `@@myvar`
2. The first ampersand is not highlighted like the rest of the line

<pre class="prettyprint lang-ruby">
class Foo
  @class_instance_var = 3
  @@class_var = 4
end
</pre>

The class instance variable is fully highlighted, but the class variable is 
not. This came about after noticing the issue on Stack Overflow. See 
http://meta.stackoverflow.com/questions/175167/bug-with-class-variable-highlight
ing-in-ruby-code-blocks.

Using revision 298, and it happens on all browsers (due to it being a regex 
issue). However, I'm using Chrome on Ubuntu.

I've attached a diff that is a potential fix to run_prettify.js, which is where 
I identified the regular expression to be. It simply adds an optional `@` to 
the regex that determines the literal, on line 1167 of the source. However, 
there may be more places where this is an issue.

Thanks
