Fix information about cleanup --compare
It fixes the information about the cleanup --compare
behavior. In case of multiple identical snapshots (no changes between them), it deletes the previous one(s) and not the next one(s) - in other words, only the last snapshot of the given state is retained. Inspired by this forum post.
See this example (there are no changes between snapshots 327 and 330):
* checking snaphot 326...
* checking snaphot 327...
* checking snaphot 328...
- Snapshot 327 deleted.
* checking snaphot 329...
- Snapshot 328 deleted.
* checking snaphot 330...
- Snapshot 329 deleted.
The snapshots 327, 328, and 329 ale deleted and 330 is kept.
This change/fix must be projected to the documentation as well.
