Description:

Running whois with -H argument supplied will return no output.

The -H flag is used to hide most legal disclaimers that are in query results provided by domain registries.

A bug was introduced in 5.2.6 upstream where the use of -H would return nothing at all.

Seems this has already been fixed by upstream: https://github.com/rfc1036/whois/commit/c5742eb115b4e1d0b6861171932aa46406d6ab87

Additional info:
* 5.2.6-1
* Fixed upstream in 5.2.7

Steps to reproduce:

`whois -H google.com` will return with nothing:

> $ /usr/bin/whois --version
Version 5.2.6.

Report bugs to <md+whois@linux.it>.

> $ /usr/bin/whois -H google.com

> $

`whois google.com` will return as normal along with legal disclaimers.

> $ /usr/bin/whois google.com
