	name: Style Checker

	# Runs my simple style(9) checker on any pushes or pull requests. It could be
	# optimized by fetching the pull request head branch back to main revisions and
	# running on that. That would reduce the run time from 3-4 minutes down to 30-40
	# seconds. Getting the right series of clone + fetches to get that iteratively
	# is proving elusive, so optimizations welcome.
