In a38e9d13 pyconfig.h.in was
manually edited and that edit was overwritten when running autoreconf.

Cease turning SyntaxWarnings into SyntaxErrors.

In case it has been previously created.

Co-authored-by: Andrew Nester <andrew.nester.dev@gmail.com>

- drop TargetScopeError in favour of raising SyntaxError directly
  as per the updated PEP 572
- comprehension iteration variables are explicitly local, but
  named expression targets in comprehensions are nonlocal or
  global. Raise SyntaxError as specified in PEP 572
- named expression targets in the outermost iterable of a
  comprehension have an ambiguous target scope. Avoid resolving
  that question now by raising SyntaxError. PEP 572
  originally required this only for cases where the bound name
  conflicts with the iteration variable in the comprehension,
  but CPython can't easily restrict the exception to that case
  (as it doesn't know the target variable names when visiting
  the outermost iterator expression)

Fix assert statement misbehavior if AssertionError is shadowed.

These were caused by keeping around a reference to the Squeezer
instance and calling it's load_font() upon config changes, which
sometimes happened even if the shell window no longer existed.

This change completely removes that mechanism, instead having the
editor window properly update its width attribute, which can then
be used by Squeezer.

Redo of #15402 by GeeTransit and Kyle Stanley.

"Arguments may be integers... " could be misunderstand as they also
could be strings.

New wording makes it clear that arguments have to be integers.

contains "return" with a non-constant value.

Fix typo in description of link to mozilla bug report writing guidelines.

Though the URL is misleading, we're indeed trying to write bug _reports_, not to add bugs.

PyConfig_Read() is now responsible to handle early calls to
PySys_AddXOption() and PySys_AddWarnOption().

Options added by PySys_AddXOption() are now handled the same way than
PyConfig.xoptions and command line -X options.

For example, PySys_AddXOption(L"faulthandler") enables faulthandler
as expected.
