Weird Bug

The result from Task Runner Explorer is different.

Steps to reproduce

1. Clone this repo
2. Open the solution file in VS, maybe you need the Node.js Tools for VS extension installed
3. Run npm install or right click the npm node and choose Install Missing npm Packages
4. Run gulp from cmd or hit Ctrl + F5 in VS
5. Bring up Task Runner Explorer
6. Right click the default task from Task Runner Explorer and choose Run
7. Compare out_server.js and out_gulp.js

Expected

Two output file should be identical.
