And if that happens anyway and a user says so, the equivalence of "I thought it was better before", we should never say "use program X instead", that should instead be handled within Emacs since that's what caused the change. The bug should of course not be re-introduced, but its solution should be transparent so the user experience will be, if desired, unchanged. -- underground experts united https://dataswamp.org/~incal
