patch 8.2.1386: backslash not removed afer space with space in 'isfname'

    patch 8.2.1386: backslash not removed afer space with space in 'isfname'

    Problem:    Backslash not removed afer space in option with space in
                'isfname'.
    Solution:   Do remove backslash before space, also when it is in 'isfname'.
                (Yasuhiro Matsumoto, closes #6651)
