No, it doesn't? This seems like crazy talk to me, like "If you're picking a substitute for saffron, blood plasma makes more sense than monocrystalline silicon". Like, what?
It makes zero sense to substitute this at all. It's exactly what it says it is, the "--hard" command line option to "git reset", and you write it in exactly one way.
Nobody is confused or disagrees about the `--hard` part. It was a minor tangent about contexts where these ASCII substitutions are established, like LaTeX (`` -> “, '' -> ”, -- -> –, --- -> —, etc.)
