Subject: [PATCH 09/16] t3415: stop losing return codes of git commands
Date: Fri, 27 Dec 2019 08:47:18 -0500	[thread overview]
Message-ID: <baf7ea00484eb7c324074e713178af2121fcd7f2.1577454401.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1577454401.git.liu.denton@gmail.com>

When a command is in a non-assignment subshell, the return code will be
lost in favour of the surrounding command's. Rewrite instances of this
such that the return code of git commands is no longer lost.
