Subject: [PATCH 2/1] do not pass "git -c foo=bar" params to transport helpers
Date: Tue, 24 Aug 2010 01:41:14 -0500	[thread overview]
Message-ID: <20100824064114.GA20724@burratino> (raw)
In-Reply-To: <20100823191600.GA2523@coredump.intra.peff.net>

Like $GIT_CONFIG, $GIT_CONFIG_PARAMETERS needs to be suppressed by
"git push" and its cousins when running local transport helpers to
imitate remote transport well.
