[issue17491] Consolidate traceback.format_tb and traceback.print_tb

[Benjamin Peterson]

Benjamin Peterson added the comment:

Thank you for the patch. It seems like it would make more sense to implement print_tb in terms of extract_tb. That is, print_tb should iterate through the result of extract_tb and do its printing.
