Subject: [PATCH v2 2/4] setup: allow for prefix to be passed to git commands
Date: Tue, 14 Mar 2017 15:10:58 -0700	[thread overview]
Message-ID: <20170314221100.24856-3-bmwill@google.com> (raw)
In-Reply-To: <20170314221100.24856-1-bmwill@google.com>

In a future patch child processes which act on submodules need a little
more context about the original command that was invoked.  This patch
teaches git to use the prefix stored in `GIT_INTERNAL_TOPLEVEL_PREFIX`
if another prefix wasn't found during the git directory setup process.
