Bug#677987: lsb-base: how do I enable fancy logging

[Ritesh Raj Sarraf <rrs@debian.org>]

Package: lsb-base
Version: 4.1+Debian7
Severity: minor

On my Debian box, which must have had an old enough installation, there
is not much intelligence I can find on how to enable fancy logging that
I keep seeing in my test VM  running newer debian.

Could this be a feature that could be enabled easily?
I tried FANCYTTY=1 in /etc/default/rcS and /etc/lsb-base-logging.sh. But
neither worked.
