Because windows users are people too!

Thanks for this and sorry for the delay.

Instead of this can you just define a constant in each file - "\n" for Unix, "\r\n" for Windows - and then write/append the constant from the string? That way we won't need the function call overhead.

Also can you rebase against master or merge in master, and squash your commits down to one commit?
