Describe the problem you're observing

After commit b3b6098, the warning message about Errata #4 has a very long line due to a missing newline at the end of the first part of the message in ``status_callback()''.

Describe how to reproduce the problem

$ zpool status
  pool: ssddata
 state: ONLINE
status: Errata #4 detected.
Existing encrypted snapshots and bookmarks contain an on-disk incompatibility.
        This may cause on-disk corruption if they are used with 'zfs recv'. action:  To correct the issue, enable the bookmark_v2 feature. No additional
        action is needed if there are no encrypted snapshots or bookmarks. If preserving
        the encrypted snapshots and bookmarks is required, use a non-raw send to backup
        and restore them. Alternately, they may be removed to resolve the
        incompatibility.
   see: http://zfsonlinux.org/msg/ZFS-8000-ER

In addition a few other lines in the action: portion of the message are longer than 80 characters when printed out.

@JMoVS Any chance you could whip up a quick PR to fix this?

[rlaager]

Based on that output, is the first line also missing a tab?

[JMoVS]

Apparently it is. I can whip up a PR and probably have it ready in ~ 16 hours, first have to sleep. May get there sooner. Sry for the trouble, I‘ll check
