The task

Also, the plural of **status** is **status** or **statuses** - not [**stati**](https://www.oed.com/search/dictionary/?q=stati): https://github.com/psf/requests/blob/f43f750ee10addbaa13901c1017631b4d70fd6e3/src/requests/models.py#L71-L73 I'd like to fix this too, but isn't `REDIRECT_STATI` pat of the API?
