zpool import output is not formated properly.

Browse Source 
The 'zpool status' output assumes that the longest prefix is six
character long plus colon plus space, eg. 'status: ', 'action: '
or 'config: ' (so eight in total). This works well even when we have
messages that requires more than one line, as '\t' is exactly eight
characters, just like the longest prefix.

The 'zpool import' output is a bit different, as it may display the
comment pool property, then the longest prefix is 'comment: ', which is
nine characters long, not eight.
All the prefixes were given an extra space in front, but:
- 'status: ' did not get an extra space.
- Messages that require more than one line should use nine spaces of
  indentation, not eight.
- The extra space in front looks redundant if there is no comment
  property set on the given pool.

Fix it by adding an extra space to all prefixes, but only if the comment
property is defined. Also, when we need to continue the message in a new
line, use '\t ' for indentation.

While here, apply small corrections to a couple messages.
