Bug#673207: /etc/default/rcS is perhaps a better place for FANCYTTY variable

Hi Stanislav, and thanks for your bugreport, 
(CC'ing the sysvinit maintainers),

After an initial perplexity, I think I now quite like this idea. From the rcS 
manpage: "rcS - variables that affect the behavior of boot scripts", so it 
would be a good fit for /etc/default/rcS.

Given that /etc/default/rcS is managed by initscripts (from src:sysvinit), I'm 
hereby asking the sysvinit maintainers: what do you think?

That said, my non-ordered and open-ended list of concerns is:

a) migrating FANCYTTY away from non-conffile /etc/lsb-base-logging.sh;
b) coping with the fact that FANCYTTY is a variable that works reversely (see 
log_use_fancy_tty function from /lib/lsb/init-functions): when /not/ defined, 
the functions use "fancy output" if possible; when defined to whatever 
negative (actually not in 1|Y|yes|true ), the functions avoid using the "fancy 
output").
c) what might I have forgotten?

Cheers,
