diff Python/traceback.c @ 1425:72bddfad351a legacy-trunk
* mpzmodule.c: cast some methods to the proper type.
* traceback.c (tb_print): use sys.tracebacklimit as a maximum number of
traceback entries to print (default 1000).
* ceval.c (printtraceback): Don't print stack trace header -- this is now
done by tb_print().
