argparse: Remove unused name variable when handling ArgumentTypeError (#96549)
This removes the unused `name` variable in the block where `ArgumentTypeError` is handled.

`ArgumentTypeError` errors are handled by showing just the string of the exception; unlike `ValueError`, the name (`__name__`) of the function is not included in the error message.

Fixes #96548

gh-88753: Make BooleanOptionalAction's addition of default to help more similar to other actions (#27808)
Help for other actions omit the default value if default is SUPPRESS or
already contains the special format string '%(default)'.  Add those
special cases to BooleanOptionalAction's help formatting too.

Fixes https://bugs.python.org/issue44587 so that default=SUPPRESS is not
emitted.

Fixes https://bugs.python.org/issue38956 as this code will detect
whether '%(default)s' has already been specified in the help string.

bpo-39716: Raise on conflicting subparser names. (GH-18605)
Raise an ArgumentError when the same subparser name is added twice to an
ArgumentParser.  This is consistent with the (default) behavior when the
same option string is added twice to an ArgumentParser.

(Support for `conflict_handler="resolve"` could be considered as a
followup feature, although real use cases seem even rarer than
"resolve"ing option-strings.)

bpo-39546: argparse: Honor allow_abbrev=False for specified prefix_chars (GH-18337)
When `allow_abbrev` was first added, disabling the abbreviation of
long options broke the grouping of short flags ([bpo-26967](https://bugs.python.org/issue26967)).  As a fix,
b1e4d1b603 (contained in v3.8) ignores `allow_abbrev=False` for a
given argument string if the string does _not_ start with "--"
(i.e. it doesn't look like a long option).

This fix, however, doesn't take into account that long options can
start with alternative characters specified via `prefix_chars`,
introducing a regression: `allow_abbrev=False` has no effect on long
options that start with an alternative prefix character.

The most minimal fix would be to replace the "starts with --" check
with a "starts with two prefix_chars characters".  But
`_get_option_tuples` already distinguishes between long and short
options, so let's instead piggyback off of that check by moving the
`allow_abbrev` condition into `_get_option_tuples`.

Zac Hatfield-Dodds dffca9e925 bpo-26967: fix flag grouping with allow_abbrev=False (GH-14316)
The `allow_abbrev` option for ArgumentParser is documented and intended to disable support for unique prefixes of --options, which may sometimes be ambiguous due to deferred parsing.

However, the initial implementation also broke parsing of grouped short flags, such as `-ab` meaning `-a -b` (or `-a=b`).  Checking the argument for a leading `--` before rejecting it fixes this.

This was prompted by pytest-dev/pytest#5469, so a backport to at least 3.8 would be great 😄  
And this is my first PR to CPython, so please let me know if I've missed anything!

zygocephalus 03d5831a2d bpo-37150: Throw ValueError if FileType class object was passed in add_argument (GH-13805)
There is a possibility that someone (like me) accidentally will omit parentheses with `FileType` arguments after `FileType`, and parser will contain wrong file until someone will try to use it. 

Example:
```python
parser = argparse.ArgumentParser()
parser.add_argument('-x', type=argparse.FileType)
```

bpo-33109: argparse subparsers are once again not required by default (GH-6919)
bpo-26510 in 3.7.0a2 changed the behavior of argparse to make
subparsers required by default, returning to the behavior of 2.7
and 3.2. The behavior was changed in 3.3 to be no longer required.
While it might make more sense to have the default to required,
compatibility with 3.3 through 3.6 is probably less disruptive
than trying to reintroduce compatibility with 2.7 at this point.
This change restores the 3.6 behavior.
