OK, I forgot a bit about this past discussion. So let's say that we
have a command, why not also allow users to use at will a marker %f to
indicate the file name just completed? One use case here is to scan
the file for the oldest and/or newest timestamps of the segment just
finished to do some retention policy with something else in charge of
the cleanup.
The option name would be --end-segment-command? Any better ideas of names?
