The message service used by git commit sometimes sends a message about every commit since the beginning of time when you push a new branch. Yesterday, this spammed every member of the larsoftcommit mailing list with thousands of messages. This needs to be fixed ASAP. Please see LArSoft bug 5678: https://cdcvs.fnal.gov/redmine/issues/5678
Perhaps it is possible to simply limit the number of messages to some small and manageable number?
