[issue23171] csv.writer.writerow() does not accept generator (must be coerced to list)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The docs mention that "row" should be a sequence, so there is no a bug.

Here is a patch which makes writerow() accept an iterable without converting it to a list. It also adds tests for few corner cases and fixes the docs.
