FN needless_return: "return" at end of void-function

[matthiaskrgr]

If we have a function that does not return a type and has return as last statement, we could suggest that that return could be omitted:

pub fn a() {
	println!("blurb");
	return; // unneeded
}

pub fn b() {
	println!("blarb");
	return // unneeded
}

=>

pub fn a() {
	println!("blurb");
}

pub fn b() {
	println!("blarb");
}

I guess this could be part of needless_return?

yeah, that's why I put it in the title :p
