    Fix formatting of version message for gnat driver
    
    Like the main driver (as well as gccgo, gccrs, gcov, etc) the gnat driver
    prints the standard version message in response to the --version switch,
    but it is not properly formatted.
    
    gcc/ada
            * gnatvsn.adb (Gnat_Free_Software): Fix message formatting.
