Some GitHub users try to open pull requests against the GitHub
mirror. Unfortunate these get ignored until eventually someone
notices and closes the request.
Enable the 'Repo Lockdown' [*] 3rd party bot which can autorespond
to pull requests with a friendly comment, close the request, and
then lock it to prevent further comments.
