These may be redefined to customize log rotation path prefixes, including use of a directory. File extensions are still up to individual log writers to add themselves during the actual rotation. These new also allow for some simplication to the default ASCII postprocessor function: it eliminates the need for it doing an extra/awkward rename() operation that only changes the timestamp format. This also teaches the supervisor framework to use these new options to rotate ascii logs into a log-queue/ directory with a specific file name format (intended for an external archiver process to monitor separately).
