Writing out an object may involve a slot lookup, which is not safe to do with
an exception raised. In debug mode an assertion failure will occur if this
happens.

The forkserver was not passing sys.argv to its main() function, causing
sys.argv to be empty during `__main__` module import in child processes. This
fixes a non-obvious regression inadvertently introduced by the gh-126631 main
preloading fix.

Copy net new text in idle.rst from main to 3.13.
Make 3.13 docs and copy-strip idle.html to idlelib/help.html.
See https://github.com/python/cpython/issues/139707#issuecomment-3737374788
and PR #143718 message for more.
* Revert url to 'main' from '3.13'
The branch in the source links in the revised help.html
become '3.13' instead of 'main' because the html
was generated from an edited 3.13 version of idle.rst
instead being backported from main. This reversion
avoids the possibility of future backport merge conflicts.
The version makes no difference to the Help/IDLE doc display as
the url is currently neither displayed nor linked to the link title
-- 'Lib/idlelib'. If we do make the links live, we can use
sys.version_info to replace 'main' when main is no longer the source branch.
It was incorrect in case of mixed tabs and spaces in indentation.

PyObject_GetBuffer() can execute user code (e.g. via __buffer__), which may
close or otherwise mutate a BytesIO object while write() or writelines()
is in progress. This could invalidate the internal buffer and lead to a
use-after-free.
Ensure that PyObject_GetBuffer() is called before validation checks.

When comparing negative non-integer float and int with the same number
of bits in the integer part, __neg__() in the int subclass returning
not an int caused an assertion error.
Now the integer is no longer negated. Also, reduced the number of
temporary created Python objects.

The unknown-8bit trick was designed to deal with unknown bytes in an
ASCII message, and it works fine for that. However, I also tried to
extend it to handle bytes that can't be decoded using the charset
specified in an encoded word, and there it fails because there can be
other non-ASCII characters that were *successfully* decoded. The fix is
simple: do the unknown-8bit encoding using the utf-8 codec. This is
especially appropriate since anyone trying to do recovery on an unknown
byte string will probably attempt utf-8 first.
