[pve-devel] [PATCH v2 guest-common 1/4] replication: prepare: adapt/expand function comment

[Fabian Ebner <f.ebner@proxmox.com>]

Commit 8d1cd44 ("partially fix #3111: replication: be less picky when
selecting incremental base") changed prepare() to return all local
snapshots.

Special behavior regarding last_sync is also better mentioned
explicitly.
