GNU ed 1.6 released

Ah, those were the days: back in the late 70s/early 80s, we had a Prime 750 running PrimOS (anybody remember those?) with an IBM-inspired line editor from the mid-60s as the system editor: if you think ed is frustrating, you should try that beast. I spent a lot of pleasant all-nighters on a terminal with a 300-baud modem porting the Kernighan & Plauger software tools to PL1/G; of course I started with ed. After that bootstrap step, there was a quantum leap in productivity (and a 1200-baud modem upgrade helped, but not as much). The ed port (and quite a few of the other tools) was actually used in the classroom for a few years, before Prime actually paid somebody to port emacs to their OS.
