This description seems to fit the purpose of diff-mode: • If this mode is appropriate only for specially-prepared text produced by the mode itself (rather than by the user typing at the keyboard or by an external file), then the major mode command symbol should have a property named ‘mode-class’ with value ‘special’, put on as follows: (put 'funny-mode 'mode-class 'special) This tells Emacs that new buffers created while the current buffer is in Funny mode should not be put in Funny mode, even though the default value of ‘major-mode’ is ‘nil’. By default, the value of ‘nil’ for ‘major-mode’ means to use the current buffer's major mode when creating new buffers (*note Auto Major Mode::), but with such ‘special’ modes, Fundamental mode is used instead. Modes such as Dired, Rmail, and Buffer List use this feature. The function ‘view-buffer’ does not enable View mode in buffers whose mode-class is special, because such modes usually provide their own View-like bindings.
