##### SUMMARY
`get_url` inherits from `add_file_common_args`, which includes `unsafe_writes`, however our call to `atomic_move` does not pass this argument along.

short_description: Downloads files from HTTP, HTTPS, or FTP to node
description:
     - Downloads files from HTTP, HTTPS, or FTP to the remote server. The remote
       server I(must) have direct access to the remote resource.
     - By default, if an environment variable C(<protocol>_proxy) is set on
       the target host, requests will be sent through that proxy. This
       behaviour can be overridden by setting a variable for this task
       (see `setting the environment
       <https://docs.ansible.com/playbooks_environment.html>`_),
       or by using the use_proxy option.
     - HTTP redirects can redirect from HTTP to HTTPS so you should be sure that
       your proxy environment for both protocols is correct.
     - From Ansible 2.4 when run with C(--check), it will do a HEAD request to validate the URL but
       will not download the entire file or verify it against hashes.
     - For Windows targets, use the M(ansible.windows.win_get_url) module instead.
