Carefully excluding t4013 and t4015, which see independent development elsewhere at the time of writing, we use `main` as the default branch name in t4*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t4*.sh t4211/*.export && git checkout HEAD -- t4013\*) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.
