	# This will be slow. The intent is to fetch all commits
	# since the merge-base (the commit where we branched off)
	# so we can check the git diff against all changed files.
	# By default, the checkout action only returns the last commit,
	# There's no native way to do this in the checkout action, so
	# we have to fetch the entire history. See
