.match honors Windows path separators on Windows

[jaraco]

Considering the match implementation:

The use of pathlib.Path here means that on Windows, a backslash will match a path separator:

>>> pathlib.Path('foo/bar.txt').match('foo\\*')
True

Perhaps that is undesirable and only posix paths should match (as those are all that are allowed in zip file separators). Perhaps PurePosixPath should be used:

>>> pathlib.PurePosixPath('foo/bar.txt').match('foo\\*')
False
