Johannes Schindelin 8f37854b18 t4*: adjust the references to the default branch name "main"
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.
