"5-line" engine

[James D Jarvis]

Man oh man this got contentious. It was a little programming fun. I see these 5-line and 10-line challenges all over the place online and they are more impressive when the editor or on interpreter can't manage hundreds of character deep lines of code.   It's just fun. But I also noted some control structures I use all the time don't work in this layout. That was a lesson for me.
