Commits IRC bot reports about commits on branches created for merge requests.
For people with developer access, creating a merge request from an issue will create a branch in the main git repo, rather than private fork.
When I pushed my patchset to that branch, the irc bot warned #nautilus room about those commits.
Not sure if relevant, but the branch's name was the GitLab's default generated name, I did not prefix it with wip/antoniof/
