IIRC, there's no such ting as "indenting two" in Python as the size of an
indentation is automatically detected as you go along, making the following
indentation style valid (although no one would ever want to do it):

toplevel
 secondlevel
                thirdlevel
 secondlevel
    thirdlevel
     fourthlevel
 secondlevel
toplevel
