"keep newest n files" makes sense to me, why would we want to keep _oldest n files_? Under what circumstance an operator would want to keep oldest around and remove the newest? Don't you think that keeping around just the latest one (or few latest ones) make more sense? This complicates the logic unnecessarily. -- This is an automated message from the Apache Git Service.
