[PATCH 0/1] diff: release all handles before running external diff

On Windows, it is not possible to overwrite a file as long as any process holds a read handle to it. Even keeping regions memory-mapped prevents that.

When git difftool calls git diff, it might be the user's intention to write the file(s) via the diff tool, so let's make sure that they are not memory-mapped at that stage.
