# Fix typo in argparse docs.
> Sometimes, when dealing with **a** particularly long argument list**s**, [...]
Mixture between plural and singular forms is incorrect. Use singular consistently since typically only a single argument list is employed. Change to:
> Sometimes, when dealing with a particularly long argument list, [...]
No issue was opened, since this is a trivial change.

Lines beginning with ``?`` try to help understanding the given diff.
The output can be hard to understand when it contains whitespace characters, such as spaces, tabs or line breaks.
While previously only tabs were mentioned, now all are listed.

We could try to remedy this by taking a slice, but we then run into an issue where the empty string will match altsep on POSIX. That rabbit hole could keep getting deeper.
A proper fix for the original issue involves making pathlib's path normalisation more configurable - in this case we want to retain trailing slashes, but in other we might want to preserve `./` prefixes, or elide `../` segments when we're sure we won't encounter symlinks.
This reverts commit ea2f5bcda1.
* Some handlers were wrongly described as text-encoding only, but actually they can also be used in text-decoding.
* Add more description to each handler.
* Add two REPL examples.
* Add indexes for Error Handler's name.

Only sequence of ASCII digits is now accepted as a numerical reference.
The group name in bytes patterns and replacement strings can now only
contain ASCII letters and digits and underscore.
Add methods enterContext() and enterClassContext() in TestCase.
Add method enterAsyncContext() in IsolatedAsyncioTestCase.
Add function enterModuleContext().
Given that 2.7 has now been end-of-life for two and a half years,
I don't think we need such a detailed explanation here anymore of
the differences between Python 2 and Python 3.
Add a closure keyword-only parameter to exec(). It can only be specified when exec-ing a code object that uses free variables. When specified, it must be a tuple, with exactly the number of cell variables referenced by the code object. closure has a default value of None, and it must be None if the code object doesn't refer to any free variables.
- add member() and nonmember() functions
- add deprecation warning for internal classes in enums not
becoming members in 3.13

Prevent `max_tasks_per_child` use with a "fork" mp_context to avoid deadlocks.
Also defaults to "spawn" when no mp_context is supplied for safe convenience.
Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.
* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
present.
One more thing that can help prevent people from using `preexec_fn`.
Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related.
