    Avoid false positives and false negatives of Info-quoted face
    
    * lisp/info.el (Info-mode-font-lock-keywords): Modify the regexp, for
    matching single quotes of opening single quote and closing single
    quote, and avoid matching text followed by a curly quote when it is
    not quoting. (Bug#35202)
