out may be a local path or a remote://... url, but os.path.exists isn't a good enough check for whether or not out is a valid local path.

In the case where we are importing with -o subdir/file, if subdir doesn't already exist it is still a valid local output path (and we need to makedirs(subdir) later)

and not contains_symlink_up_to(abspath, repo.root_dir)
):
wdir = dirname
