[PATCH 09/16] t3415: stop losing return codes of git commands

From
Denton Liu <liu.denton@gmail.com>
Date
Dec 27, 2019, 13:47 UTC
Message-ID
<baf7ea00484eb7c324074e713178af2121fcd7f2.1577454401.git.liu.denton@gmail.com>
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.
