Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA).

Unfortunately we couldn't find an account corresponding to your GitHub username on bugs.python.org (b.p.o) to verify you have signed the CLA. This is necessary for legal reasons before we can look at your contribution. Please follow these steps to help rectify the issue:

1. If you don't have an account on b.p.o, please create one
2. Make sure your GitHub username is listed in "Your Details" at b.p.o
3. If you have not already done so, please sign the PSF contributor agreement
4. If you just signed the CLA, please wait at least a day and then check "Your Details" on bugs.python.org to see if your account has been marked as having signed the CLA (the delay is due to a person having to manually check your signed CLA)
5. Reply here saying you have completed the above steps

Thanks again to your contribution and we look forward to looking at it!

I don't think small fix like this doesn't require CLA sign.
But please wait for confirm from other core dev.

I'm sorry. CLA is required.

Why is this change tagged with "backport to 3.6"? Was it made in the 3.6 branch? If yes, I suggest to only modify master.

Broken links, typo fixes, comment updates etc. usually go to all maintenance branches. 'backport to X.Y' label means this needs to be backported to X.Y branch.

I have completed the above steps.

Thanks, friends!

Don't forget to update Python 2.7 as well.
