HN forum software is inadequate to represent initial spacing. I replaced it with more hyphens. It wasn't intentional as you can tell from the first 'simulated post' which has no code formatting.
I made my own user stylesheet for HN a looong time ago, so why would I email anyone? I showed a simple fix, but oh well. If I wanted to paste something big in block formatting I would put it on pastebin, in this context I'm just a bystander trying to help people with a problem I don't have.
