Care for correctness was much more of a thing, when coding was a rare art and not a copy/paste from stack overflow to finish this week's sprint on time. There was also a lot less code in general so I would expect every line to be considered in much more detail. Also, 'laziness' tends to be a character flaw that manifests itself everywhere in a person's work, not just in one place. And Richie/Kernighan don't exactly have a bad reputation. I wonder if the '-a' parameter of ls appeared at the same time. If so it definitely wasn't an oversight.
