Should document this change.

Hello. A user here.

Can you update the PR to include another list-specific option to change the end text, too?

Maybe an option called listOpts can take an object having these two parameters because we wouldn't want to crowd the main options too much.

Actually, there is no specific List option to this end text, it refers to its Paginator util. Anyways, I made that change and now you could custom it, check my latest commit :D

I've never worked with testing before, but I'll try it~

I tried to make the unit test, and went well (I guess).
