commit b622a8b55d5a640ef592fffdebb5a008ea2361fa
Author: Bastien Nocera <hadess hadess net>
Date:   Mon Oct 21 13:19:16 2019 +0200

    ci: Print all the commits that need bug references
    
    Rather than just the latest one, otherwise it might leave the patch
    submitter to iterate over every commit, if they didn't know every patch
    needed a reference.
    
    Closes: #1809
