Several typos in Higher order components documentation

[gamtiq]

It seems there are the following issues in Higher order components documentation.

Example for withRefs contains the following code:

let sectionElement;
const enhance = withRefs(component => ({
    section: el => {
        sectionElement = el;
        return {
            unsubscribe() {
                sectionElement = el;
            }
        };
    }
});

I suppose unsubscribe function should have the following line:

sectionElement = null;

A couple of typos:

When props are given the the component the RECEIVE_PROPS action will be called with the props as its payload.
These are higher-order functions that accept a set of props and return a function handler*:* This allows the handler

Also description of handlersCreators parameter of withHandlers below signature is incorrect.
