Here's a first attempt at adding such a feature, which would by default create
a new full backup every half of the keep period.
So for instance, if one keeps backups for 60 days, a full new backup will be
created every 30 days, so 2 complete full will be kept, without accumulating
too many incrementals.
Any comments welcome.
