Hey @RAbraham - so it does seem that in the 1.X family of Jekyll releases,
the "highlighter" option does not exist:
https://github.com/jekyll/jekyll/blob/1.0-branch/lib/jekyll/configuration.rb
So I'm inclined to leave this as-is for the moment since the current
approach technically works with both versions. A lot of Spark packagers install
jekyll with package managers and I think those aren't up to Jekyll 2.0 yet in
most cases. So I think we should close this issue for now, but revisit it down
the road.
