I changed that.

Though, to be honest, perhaps we should replace this entire example with
something that actually demonstrates _why_ one would want to use `rx'.
I just couldn't think of a good example right now.  There is time to
improve the example before Emacs 28.1, I guess.

I added all of them into a new section and pushed this to master.
