+5.13 long paths are not fully supported on Windows

+ curl on Windows cannot access long paths (paths longer than 260 characters).
+ However, as a workaround, the Windows path prefix \\?\ which disables all path
+ interpretation may work to allow curl to access the path. For example:
+ \\?\c:\longpath.
