These two tests could be a single test.

	test_expect_success 'checkout --orphan warns on orphan commits' '
		git checkout "$orphan2" &&
		git checkout --orphan orphan 2>stderr &&
		check_orphan_warning stderr "2 commits"
	'

Validating output like this in a separate step is an artifact of
the old way of checking localized strings.  Tests were split into
two in f06f08b78c ("i18n: mark checkout plural warning for
translation", 2011-04-10) and then prerequisite C_LOCALE_OUTPUT
was removed in f2c8c8007c ("i18n: use test_i18ngrep in t2020,
t2204, t3030, and t3200", 2011-04-12).  Usage of test_i18ngrep
was then removed in 1108cea7f8 ("tests: remove most uses of
test_i18ncmp", 2021-02-11).
