    Optimise ‘never dim’ check
    
    All minibuffers are hidden buffers (i.e. ones whose name starts with
    a space) so ‘minibufferp’ check in ‘adob--never-dim-p’ function was
    redundont.
    
    Furthermore, the function was never called from a place where the
    argument colud be nil so ‘null’ check was unnecessary as well.
    
    What remains is checking whether buffer’s name starts with a space
    so change ‘adob--never-dim-p’ to do just that.  For good measures,
    inline ‘string-prefix-p’ and call ‘compare-strings’ directly thus
    eliminating a few function calls.
