I have just added PR #12828, based off issue #12764 to clarify some of the documentation of `nditer`. While it contains most of the necessary material, it's still a bit of a rough draft, and I'd be happy to have some comments/advice on it.

In particular, I didn't know how much to emphasize the fact that context management only became a thing for `nditer` in version 1.15.0. I'm also not sure about how much need there is to reiterate the C-style iteration methods vs the normal Python-style iteration.
