### Summary

The `get_url` module documentation has extraneous formatting in the "not" word in:
```
NTLM authentication is C(not) supported even if the GSSAPI mech for NTLM has been installed.
```
As it is a part of a sentence, I suspect the "not" here should not have any specific formatting.

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 R(setting the environment,playbooks_environment)),
       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.
