rear master

During #882 (comment) I noticed messages on the screen
that are not logged in the rear log file.

I did "rear -d -D recover" and got this on the screen
(excerpts - long lines wrapped):

RESCUE g130:~ # rear -d -D recover
...
Creating filesystem of type btrfs with mount point / on /dev/sda3.
8 bytes [5f 42 48 52 66 53 5f 4d] erased at offset 0x10040 (btrfs)

Btrfs v3.18.2+

ATTENTION:

mkfs.btrfs is not intended to be used directly. Please use the
YaST partitioner to create and manage btrfs filesystems to be
in a supported state on SUSE Linux Enterprise systems.

But in /var/log/rear/rear-g130.log (in the running recovery system)
there is only (excerpt - long lines wrapped):

I.e. nothing at all in the log about

Btrfs v3.18.2+

Perhaps this is a general missing functionality in rear
that everything what appears on the screen is also logged?

@gdha
do you know if everything what appears on the screen
should also be logged when '-d' and '-D' is used
or do I do something wrong?
