Subject: [PATCH v2 21/27] t7[5-9]*: adjust the references to the default branch name "main"
Date: Tue, 17 Nov 2020 16:12:21 +0000	[thread overview]
Message-ID: <2b269ca98392c6d4da3831b334c8c3b823228e60.1605629549.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.762.v2.git.1605629547.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

Excluding t7817, which is added in an unrelated patch series at the time
of writing, this adjusts t7[5-9]*. This trick was performed via

	$ (cd t &&
	   sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
		-e 's/Master/Main/g' -- t7[5-9]*.sh)

This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.
