PrintlnFunc is not compatible to fmt.Println

[jojomi]

What do you think about PrintlnFunc returning a func compatible to fmt.Println regarding to the return params?

Something like this:

// PrintlnFunc returns a new function that prints the passed arguments as
// colorized with color.Println().
func (c *Color) PrintlnFunc() func(a ...interface{}) (int, error) {
    return func(a ...interface{}) (int, error) {
        return c.Println(a...)
    }
}```

This came up before if you search for the Closed PR's or issues. The problem is that this breaks the API and this package is right now imported by hundreds of other packages. It's like this now forever (until I release a breaking version, which I don't want to right now). Thanks
