### 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.

        time and replace the file if the contents change. If C(no), the file

        should be C(yes) only for small local files.
      - Prior to 0.6, this module behaved as if C(yes) was the default.
