That's odd; in the master sources GREP_OPTIONS still works; it's just that it's 
deprecated and issues a warning. Perhaps Debian has changed that?

Anyway, GREP_OPTIONS is deprecated because of correctness and security issues 
caused by having environment variables change the behavior of standard commands. 
If you want your grep to default to -i, you can create a script called 'grep' 
that invokes /usr/bin/grep -i, and put your script in your PATH before /usr/bin.
