From b2e92a712ea7316563c5115639c1e39ad6c5a09b Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>

Subject: Fix getopt-vs-init_ps_display problem by copying original argv[]
 info, per suggestion from Peter.  Simplify several APIs by transmitting the
 original argv location directly from main.c to ps_status.c, instead of
 passing it down through several levels of subroutines.
