    patch 9.0.1601: filetype detection fails for *.conf file without comments

    Problem:    Filetype detection fails for *.conf file without comments.
                (Dmitrii Tcyganok)
    Solution:   Use "conf" filetype as a fallback for an empty .conf file.
                (closes #12487, closes #12483)
