Add cwd argument to Python 3 stubs for subprocess calls. - #889

Maybe you should check all the functions in that stub take all the possible keyword arguments.

I agree that it's totally worth doing eventually. I myself intend to do it, even (no promises though). But I would prefer to do it in a separate PR, unless the owner insists. For now I'm just testing the waters, how contribution to this project works (for instance, whether I'll be asked to send this patch to typeshed instead, or I don't know what).

In addition, I'm reasonably confident in this trivial change, while updating all keyword arguments is much more error-prone, as they are scattered across module documentation.

Yes, sending an (additional?) PR to http://github.com/python/typeshed would make a lot of sense.
(Until #884 is merged, all stubs changes should probably happen in both repositories, to keep things in sync)

Yeah, until we have a complete stub story sending PRs to typeshed as well would be appreciated (but not necessary). Also, it's totally fine to send only small updates or fixes to stubs such as these.

And thanks for the PR!

Applied this change to http://github.com/python/typeshed as well.
