Bug#953075: debian-reference: Incorrect environment example for 'date' in section 1.5.2

[Hank Knox]

I am a little embarrassed. A little digging revealed all the LC_ 
variables are set in /etc/locale.conf. I'm not sure how that file got 
set but the date suggests it was around the time I installed Debian. So 
either it came from a long-ago config file or something prompted me to 
set it. I think we can close this bug.
