This parallels the implementation of windowsDiff.Apply, including bouncing very briefly though archive.WriteDiff and then straight back out into Windows-specific code. It's mostly pulling existing mechanisms from non-Windows Compare or Windows Apply, and highlights that there's probably a lot of scope for refactoring on top of this. Now the export-related integration tests pass CI on Windows. Signed-off-by: Paul "TBBle" Hampson <Paul.Hampson@Pobox.com>
