preserve trailing back-slashes in NativePath

[MartinNowak]

Slash behavior originally introduced here 970a022#diff-3620332feace439ec637b023bc2e7a01R262, and apparently broken here 344fe34#diff-47d6be40e29a186df00d5f3bfad92671R36.

The weird usage of Path for URLs and file paths on Windows makes this difficult to handle properly (though / and \ usage should be mut-ex IIRC). No idea how much impact this breaking change would have. Any suggestion for a better migration path?

This is why there are three default path types in vibe-core (WindowsPath, PosixPath and InetPath). This conflation was a really bad idea, one that std.path also suffers from.

It should be m_endsWithSlash |= pathstr.endsWith('\\'); though, so that a trailing slash is also still allowed on Windows.

Of course 🙄, done.
