Close open Github pull requests and prevent / auto-close new ones.
I just stumbled over LO's read-only Github clone and saw it has various old and open pull request with some hilarious content, where Github somehow matches core commits to them. Looking for an better solution, I found https://github.com/dessant/repo-lockdown, which claims to be able to auto-close pull request, since it's still impossible to disable them in Github.
Also the repo text refers to gerrit.libreoffice.org. Maybe it's better to point people to https://wiki.documentfoundation.org/Development, since LO development involves more then just a Gerrit push.
Thanks for considering this improvement.
