Fixed spacing for better consistency

Fixed the spacing in code-reuse-patterns/prototypal-inheritance.html for better consistency.

For example, from:

// create a new person
var papa = new Person();
// inherit
var kid = object(papa);
// test that both the own property
// and the prototype property were inherited
console.log(kid.getName()); // "Adam"

to:

// create a new person
var papa = new Person();

// inherit
var kid = object(papa);

// test that both the own property
// and the prototype property were inherited
console.log(kid.getName()); // "Adam"
