Thanks for reviewing, @pitrou !

@pitrou: You merged the commit message with the sentence:

@vstinner / @corona10, would you mind reviewing this?

And I'm now getting emails from cpython forks, like this commit:

JelleZijlstra@01c6aa4

[pitrou]

Ah, sorry. I get this sometimes when my name is mentioned too :-)

[vstinner]

Ah, sorry. I get this sometimes when my name is mentioned too :-)

Well, the "automerge" label causes a similar feature and it's part of our workflow. I'm not sure how to ignore such emails. @pganssle has such issue: https://twitter.com/pganssle/status/1379161385863643155

[erlend-aasland]

It's partly my fault; I cc'd you in the PR text instead of in a separate comment/post. After this incident, I've made sure I don't mention anyone in the PR text. Maybe it could be mentioned in the Dev Guide? Maybe we could make the CI prevent it by rewriting the commit message (if needed) upon merging.

I asked how to not get spammed on python-committers: https://mail.python.org/archives/list/python-committers@python.org/thread/OCVQ6IYOVTVYW7ADDNOHKR7JDRBYLM3T/
