From 68d442ddaf878955395a4fbc9d11d6437b93ee1e Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Mon, 18 Feb 2002 12:33:11 +0000
Subject: When getting input via a pipe, apply the environment settings to the
 command in question, not to `cat'. No longer allow more than one element in
 the $Test::env or $Test::env_default arrays.  No one used that.
