flag to control Windows pattern expansion

[davidism]

Windows terminals don't do pattern expansion, so #1096 requested simulating it in Click. However, Windows also doesn't have a way to escape patterns so that the literal value is used. This adds a flag cli(windows_expand_args=False) to disable expansion.

• fixes Allow disabling pattern expansion on Windows #1901

How is this used? I tried:

import click

@click.group(windows_expand_args=False)
@click.pass_context
def cli(ctx):
    ...

and

import click

@click.group(context_settings={'windows_expand_args': False})
@click.pass_context
def cli(ctx):
    ...

It's an argument to the main program.

cli(windows_expand_args=False)

How would you define that in an entrypoint though? Like: https://github.com/DataDog/integrations-core/blob/2fc7c56e9aadf3393462cff97709bca6714b3487/datadog_checks_dev/setup.py#L99

Define another function (or use functools.partial) and point the entry point at that.

def main():
    cli(...)
