Thanks! Committed as r66829.

I've added additional documentation in r66830, which should complete
Guido's list of things to be documented. So the issue can be closed
now.

We should discuss that on python-dev, of course - the question is
whether additional documentation patches are needed in response to
this specific change.

I was probably looking at the wrong patches (such as getcwd_bytes.patch,
merge_os_getcwd_getcwdu.patch, etc); I now see that the final patch did
have tests. I recommend that patches that get superseded by other
patches are removed from the issue. The won't be deleted; it's still
possible to navigate to them through the History at the bottom of the
issue.
