I can't imagine!  Probably something more like:

function Next_Line(File : in Ada.Text_IO.File_Type := 
   Ada.Text_Io.Standard_Input) return String is
   Answer : String(1..256);
   Last   : Natural;
begin
   Ada.Text_IO.Get_Line(File => File,
      Item => Answer,
      Last => Last);
   if Last = Answer'Last then
      return Answer & Next_Line;
   else
      return Answer(1..Last);
   end if;
end Next_Line;
