This Monty Python reference is of-its-time. It could seem inappropriate in the context of today's sensibilities around mental health.

* gh-93883: elide traceback indicators when possible
Elide traceback column indicators when the entire line of the
frame is implicated. This reduces traceback length and draws
even more attention to the remaining (very relevant) indicators.
Example:
```
Traceback (most recent call last):
File "query.py", line 99, in <module>
bar()
File "query.py", line 66, in bar
foo()
File "query.py", line 37, in foo
magic_arithmetic('foo')
File "query.py", line 18, in magic_arithmetic
return add_counts(x) / 25
^^^^^^^^^^^^^
File "query.py", line 24, in add_counts
return 25 + query_user(user1) + query_user(user2)
^^^^^^^^^^^^^^^^^
File "query.py", line 32, in query_user
return 1 + query_count(db, response['a']['b']['c']['user'], retry=True)
~~~~~~~~~~~~~~~~~~^^^^^
TypeError: 'NoneType' object is not subscriptable
```
Rather than going out of our way to provide indicator coverage
in every traceback test suite, the indicator test suite should
be responible for sufficient coverage (e.g. by adding a basic
exception group test to ensure that margin strings are covered).
The traceback.c and traceback.py mechanisms now utilize the newly added code.co_positions and PyCode_Addr2Location
to print carets on the specific expressions involved in a traceback.

The format_exception(), format_exception_only(), and
print_exception() functions can now take an exception object as a positional-only argument.

In the documentation for the traceback module, the definitions of functions
extract_tb(), format_list() and classmethod StackSummary.from_list()
mention the old style 4-tuples that these functions used to return or accept.
Since Python 3.5, however, they return or accept a FrameSummary object
instead of a 4-tuple, or a StackSummary object instead of a list of 4-tuples.

Large sections of repeated lines in tracebacks are now abbreviated as
"[Previous line repeated {count} more times]" by both the traceback
module and the builtin traceback rendering.
Patch by Emanuel Barry.
Provide a way to seed the linecache for a PEP-302 module without actually
loading the code.
Provide a new object API for traceback, including the ability to not lookup
lines at all until the traceback is actually rendered, without any trace of the
original objects being kept alive.
it yet since sphinx can't run the doctests using python3.

Make sys.xxx variable references into links, note that print_last only
works when an exception gets to the interactive prompt, and update the
examples after testing. The last one is now a valid Sphinx doctest,
but of the preceding two one can't be made a doctest and the other one
I'm postponing to 3.x because sphinx handles doctests as Unicode strings
and that makes the 2.x output confusing.

This "fixes" compilation issues for the Carbon._OSA module on OSX Leopard
by purging bindings to OSA's debug API's. Those APIs we're completely
unsupported on OSX 10.4 and are no longer available on OSX 10.5.
Note that this patches a generated file. This is somewhat acceptable because
regenerating the file is non-trivial and wouldn't use system headers anyway.
