TypeScript syntax highlighting breaks in case the return type of a function ends with a number

• VSCode Version: 1.0.0
• OS Version: Windows 8.1 and Windows 10

Steps to Reproduce:

1. Create a typescript file
2. Insert the following code:

import {Vector3, Vector} from 'vectors';

/**
 * A simple 3x3 matrix structure.
 * 
 * @export
 * @class Matrix3x3
 */
class Matrix {
 public M11 : number;
 public M12 : number;
 public M13 : number;
 public M21 : number;
 public M22 : number;
 public M23 : number;
 public M31 : number;
 public M32 : number;
 public M33 : number;


 /**
 * Gets a column as a new vector.
 * 
 * @param {number} index The index of the column (0 .. 2).
 * @returns {Vector3} A vector representing the column.
 */
 public getColumn_Breaks(index : number) : Vector3 {
 if (index == 0) {
 return new Vector3(this.M11, this.M21, this.M31);
 } else if (index == 1) {
 return new Vector3(this.M12, this.M22, this.M32);
 } else if (index == 2) {
 return new Vector3(this.M13, this.M23, this.M33);
 } else {
 throw new RangeError('Invalid matrix 3x3 column index: ' + index);
 }
 }

 /**
 * Gets a column as a new vector.
 * 
 * @param {number} index The index of the column (0 .. 2).
 * @returns {Vector3} A vector representing the column.
 */
 public getColumn_Works(index : number) : Vector {
 if (index == 0) {
 return new Vector(this.M11, this.M21, this.M31);
 } else if (index == 1) {
 return new Vector(this.M12, this.M22, this.M32);
 } else if (index == 2) {
 return new Vector(this.M13, this.M23, this.M33);
 } else {
 throw new RangeError('Invalid matrix 3x3 column index: ' + index);
 }
 }

}

Fun fact: Seems even the GitHub highlighter can not handle that specific case :|

Moving to Microsoft/TypeScript-TmLanguage for investigation.
