I've never liked that paragraph and find the
documented behavior is much less useful than the
proposed behavior.

With the documented behavior, the effect is "rotate
at this size, but no more often than XXX time interval",
which serves to limit the number of log files created,
but not the total size.  In practice, /var/log total
size is almost always the critical resource.

If compatibility is essential, perhaps we could
add a new flag to control this behavior.  (I would
argue for changing the default and providing a flag
to obtain the old behavior.)
