[New-bugs-announce] [issue26318] `io.open(fd, ...).name` returns numeric fd instead of None

[Марк Коренберг]

New submission from Марк Коренберг:

`io.open(fd, ...).name` returns numeric fd instead of None. This lead to some nasty bugs.

In order to bring consistency and make that predictable, please make `.name` for that case to return None. (and document it)
