Summary: sys.excepthook

Initial Comment:
This patch separates out the traceback-displaying
functionality of PyErr_PrintEx into a new routine,
PyErr_Display(exc, val, tb).  PyErr_PrintEx finds and
calls sys.excepthook, and the new function
sys.excepthook calls PyErr_Display.

This allows user customization of top-level exception
handling (in particular, you can write Python routines
to install as sys.excepthook that display function
arguments or format tracebacks nicely in HTML for CGI
scripts).

This is a minimal patch just to implement
sys.excepthook.
A more complete patch, postponed for 2.2, factors out
the SystemExit handling in PyErr_PrintEx into a
separate
routine and replaces all of the C code in PyErr_Display
and PyTraceBack_Print with shorter, more maintainable
Python code in the traceback module.
