Based on what's described here [0] and above, I get the impression that RMS deliberately left the copyright for the parts of gosmacs he had retained in the interim - that he had the impression that he was permitted to use those parts and wasn't even trying to hide it. I find it hard to believe that RMS was simply removing copyright from other listings. In his description found in [0], he was replacing a lot of it while using the display portion. Presumably that's all replaced after the lawsuit. The history of EMACS and TECO predate Gosmacs, this all seems rather silly. "EMACS is available for distribution to sites running the DEC Twenex operating system. It is distributed on a basis of communal sharing, which means that all improvements must be given back to me to be incorporated and distributed."
