Using environment variable may cause problems.
It forces users using ps(1) in shell scripts to be aware of the variable,
and every existent script needs being rewritten so as not to be affected
by user settings.
I suggest either
1. make it a separate program, such as
/usr/bin/ps-sysv, /usr/5bin/ps, etc., or
2. implement it using command-line option
ex. "ps -A" for AT&T / "ps -B" for Berkeley.
