Sorry, Here I mean:

Do you mean combine step 3 and step 4 together? Currently step 3 is just to 
compute the biggest width value and step 4 is to compute exact width and do the 
convert work(by calling 
PyObject_Str()/PyObject_Repr()/PyObject_ASCII()/PyUnicode_DecodeUTF8() for 
%S/%R/%A/%s). Only by doing convert we can get the exact width of a string. So 
I have to compute each width twice in both step 3 and step 4. Is combining the 
two steps in to one a good idea?
