Subject: [PATCH 3/4] run-command: move envvar-resetting function
Date: Tue,  1 Jun 2021 14:34:18 -0700	[thread overview]
Message-ID: <c5307a9f02f3f0f9b30c87bb3e9f8fa3163f839d.1622580781.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1622580781.git.jonathantanmy@google.com>

There is a function that resets environment variables, used when
invoking a sub-process in a submodule. The lazy-fetching code (used in
partial clones) will need this function in a subsequent commit, so move
it to a more central location.
