    Align to prev sibling for c-ts-mode indentation
    
    As requested by a discussion on emacs-devel.
    
    * lisp/progmodes/c-ts-mode.el:
    (c-ts-mode--anchor-prev-sibling): New function.
    (c-ts-mode--indent-styles): Indent first child as before, indent the
    rest to their previous sibling.  Remove bracketless statement rules
    that I forgot to remove previously.
