Lines 478 to 500 in d52b326

	/// Prints the error and exits.
	///
	/// Depending on the error kind, this either prints to `stderr` and exits with a status of `1`
	/// or prints to `stdout` and exits with a status of `0`.
	pub fn exit(&self) -> ! {
	if self.use_stderr() {
	// Swallow broken pipe errors
	let _ = self.print();
	if self.wait_on_exit {
	wlnerr!("\nPress [ENTER] / [RETURN] to continue...");
	let mut s = String::new();
	let i = io::stdin();
	i.lock().read_line(&mut s).unwrap();
	}
	safe_exit(USAGE_CODE);
	}
	// Swallow broken pipe errors
	let _ = self.print();
	safe_exit(SUCCESS_CODE)
	}

As per #1327, the USAGE_EXIT code is now 2, but the documentation still states that it exits with code 1.
