In addition to the current mess, we also keep Copyright header even if the code holding such Copyright had been removed since. Legally speaking, I think =E2=80=93 although I am not totally sure =E2=80=93 the co= pyright applies to the current source code and not to the history of additions. > info '(maintain) Legally Significant' offers as advice that changes of > 15 lines or less or not legally significant for copyright. For the interested reader, it comes from the package =E2=80=99gnu-standards= =E2=80=99, also online: https://www.gnu.org/prep/maintain/html_node/Legally-Significant.html#Legall= y-Significant Cheers, simon
