Module variable name

[Salvatore Filippone]

The example I have is like Richard's first, 
specifically: 

module string 
  interface tolower
    function  tolowerc(string)
      character(len=*), intent(in)  :: string
      character(len=len(string))    :: tolowerc
    end function tolowerc
  end interface
end module string


Based on Richard's comment, I believe I have to open a PR (not until
tomorrow, though)

Thanks to all
