win32lfn-python3

This is a modified version of the original extension that supports Python 3. It's not extensively tested yet but it seems to be working for me on Windows 10 (build 19045) with Mercurial/TortoiseHg 6.5.1 (which appears to bundle Python 3.9.13).

Python 3 appears to have fixed some issues with handling of long paths, so less work required by this extension to fix issues. I've commented out a few lines that appear to be no longer necessary.

Feel free to open issues and PRs and I'll do my best to accomodate.

Original Readme

Mercurial extension which allows using working copies that contain filenames longer than Windows MAXPATH of 260 characters.
