From ab88c36321df647e17d477f19591cf6ca95de7f0 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 6 Feb 2008 05:11:18 -0500 Subject: [PATCH] allow suppressing of global and system config The GIT_CONFIG_NOGLOBAL and GIT_CONFIG_NOSYSTEM environment variables are magic undocumented switches that can be used to ensure a totally clean environment. This is necessary for running reliable tests, since those config files may contain settings that change the outcome of tests.
