    Rename logos-focus-mode-hook for correctness
    
    The 'logos-focus-mode-extra-functions' has the unfortunate connotation
    of being an irregular hook, i.e. one that is called with arguments.
    Whereas this one is a regular hook that passes no arguments to the
    functions it calls.
    
    Quoting from the Emacs Lisp Reference Manual:
    
           If the hook variable’s name does not end with ‘-hook’, that indicates
        it is probably an “abnormal hook”.  These differ from normal hooks in
        two ways: they can be called with one or more arguments, and their
        return values can be used in some way.  The hook’s documentation says
        how the functions are called and how their return values are used.  Any
        functions added to an abnormal hook must follow the hook’s calling
        convention.  By convention, abnormal hook names end in ‘-functions’.
    
    To read the manual, evaluate:
    
        (info "(elisp) Hooks")
