![Ævar Arnfjörð Bjarmason](/assets/img/avatar_default.png)
Change tests that used a "mkdir -p .git/hooks && write_script" pattern to use the new "test_hook" helper instead. The new helper does not create the .git/hooks directory, rather we assume that the default template will do so for us. An upcoming series[1] will extend "test_hook" to operate in a "--template=" mode, but for now assuming that we have a .git/hooks already is a safe assumption. If that assumption becomes false in the future we'll only need to change 'test_hook", instead of all of these callsites. 1. https://lore.kernel.org/git/cover-00.13-00000000000-20211212T201308Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

recreating merge commits.
