The separator will always be required (even if you use multiple %(trailer) blocks), because it overrides the default of terminating with a newline. And we can't switch that default without breaking compatibility for existing users. So I think after my series you'll have: %(trailers:key=Files,separator=) %(trailers:key=Duration,separator=) or similar. -Peff
