[Borgbackup] borg prune behaviour

[nicrel at arcor.de]

Hi everybody,
I'm trying to prune my very first borg repo created on 2016-05-25.

I tried dry-run param to have an idea of what it would prune when leaving only 7 days daily backups.

When running the suggested command from the documentatioin site, from the command line output I got, I would consider no files to be deleted?

Can somebody shed some light on this issue?

>From documentation, I had expected pruning of all archives apart from (keep the last 7 daily ones):

Summary might be correct (0 bytes gained, as I have probably only added files); but wouldn't borg at least list the archive tags that will be removed?
