Is the comma by choice?

Can it be removed from the Summary of this PR?

----------------
Now that there is a 2018 standard, I am assuming that f18 and F18 are also valid fortran extensions. Can these be added to the File types?

Also, should the TypeInfo file be extended to handle all Fortran file types? ./include/clang/Driver/Types.def

Also, should we capture some information about the standards from the filename extension?

-config.suffixes = ['.c', '.cpp', '.h', '.m', '.mm', '.S', '.s', '.f90', '.f95',
+config.suffixes = ['.c', '.cpp', '.h', '.m', '.mm', '.S', '.s', '.f90', '.F90', '.f95',
                    '.cu', '.rs', '.cl', '.hip']
----------------
For completion .F95 also?
Should we add f03,F03,f08,F08,f18,F18. May be not now.
