I made Fedora package for nsdiff, which got now PR https://src.fedoraproject.org/rpms/nsdiff/pull-request/2. That updates used license. But License text is required in source archive by Fedora Packaging Guidelines. Can be text both of 0BSD and MIT-0 added to separate file, called COPYING or LICENSE?
