ignore-existing=true doesn't work on Windows

[tlynn]

When dest exists, shutil.move calls shutil.copytree, calls os.makedirs, call os.mkdir(dest), which throws an error. This is on Windows, but it's in keeping with the docs for move, copytree and makedirs. The problem shows up on Windows because on other platforms shutil.move usually manages to use os.rename to implement the move. When src and dest are on different filesystems you'd probably get the same issue.

Should be fixed with 0b9f58c, can you confirm?
