Done, or at least I don't see other formatting issues. Let me know if I
missed something.

Fixed. I've kept use_log_agg only and I've removed the default. Also
I've added one more check (that the total duration is a multiple of
the aggregation interval).

And just as with the sampling patch, I believe the "-l" should not be
enabled by default, but required. But if more people ask to enable it
whenever the aggregation or sampling is used, I'm fine with it.
