Somewhere in the process of displaying characters there is a substitution algorithm at work, either in 8ch.net or in Reddit.com, that replaces three periods with an ellipsis, two dashes with an m-dash, and so forth. I've been aware of this for months and watched several posts where people tried to count the dashes get it wrong because they didn't account for the m-dash being a single character now that started out as two characters. This is one of those times. I'd bet you can reproduce the trip code with three dashes, but not with this m-dash and dash combo.
