NoWhitespaceBefore: Add support for varargs

[cypai]

I was surprised to see that NoWhitespaceBefore does not support varargs:

$ javac Test.java 
$ cat Test.java
public class Test {
    public static void main(String ... args) {} // Would like to have a violation here
}

There's no easy regex for this, so it would be nice to have this addition.

I even surprised it is compilable, I have never seen such a code.

This token should be in set of defaults
