Subject: [PATCHv4 3/5] t7406: avoid having git commands upstream of a pipe
Date: Wed,  8 Aug 2018 09:31:05 -0700	[thread overview]
Message-ID: <20180808163107.12329-4-newren@gmail.com> (raw)
In-Reply-To: <20180808163107.12329-1-newren@gmail.com>

When a git command is on the left side of a pipe, the pipe will swallow
its exit status, preventing us from detecting failures in said commands.
Restructure the tests to put the output in a temporary file to avoid
this problem.
