[docs] [issue34713] csvwriter.writerow()'s return type is undocumented

[Rémi Lapeyre]

Rémi Lapeyre <remi.lapeyre at henki.fr> added the comment:

Issue #27497 is related, it adds documentation a return value and documentation to csv.DictWriter.writeheader which uses writerow internally. 

In the discussion, @lsowen found code that uses it at https://docs.djangoproject.com/en/1.9/howto/outputting-csv/#streaming-large-csv-files.

Given that this behavior has been added to csv.DictWriter.writeheader it makes sense to document csv.Writer.writerow. Do you want to post a pull request?
