Thanks @erlend-aasland!

Just to record the action somewhere, I also adjusted branch protection rules to prevent deletion of mpdecimal and libffi, and removed some dead branches (openssl, openssl-1.0.2, openssl-1.1.1, tk85, tcl85, bsddb, and tix). The tags from the old branches are still there, and there were no un-tagged commits on those branches.
