[Borgbackup] borg prune behaviour

[nicrel at arcor.de]

Hi Adrian,
thanks for your quick response!

That solved my issue immediately.

Anyways, I'd suggest to add --list to examples shown on https://borgbackup.readthedocs.io/en/stable/usage.html#borg-prune.

There it says "It is strongly recommended to always run prune --dry-run ... first so you will see what it would do without it actually doing anything." but with the examples shown, you just don't see what it would acutally be doing as --list is missing from the examples...

Maybe even setting --list as default for prune would be a good idea?

Best regards,
Carsten
