Extra backslashes?

I'm sending this as a pull request mostly in jest. But since I don't know any C, I decided to clone your code and play with it. As I mentioned in Issue #1, my output had a bunch of extra backslashes in it. So, bascially, I went through a removed what appeared to be a bunch of extra double backslashes, `\\`. So my output now looks like this:
