Chapter 1, ssh config is being used

I'm sorry if this was already reported, but on page 6 the book mentions

> If you’re not using port 22 for SSH on this server, you will need to add it to the address, like www.example.com:2222, since Ansible defaults to port 22 and won’t get this value from your ssh config file

Which I believe is not true. With this inventory file
```ini
[test]
127.0.1.1
```
and this in `~/.ssh/config`
```
Host 127.*
port 2222
```
When I run `ansible -i inv test -m ping` I get
```
127.0.1.1 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: ssh: connect to host 127.0.1.1 port 2222: Connection refused",
"unreachable": true
}
```

One thing I noticed is that there is some sort of caching. If i remove the offending lines config from ssh config and use ansible it works as expected. After that if I re-add the two lines to ssh config ansible still uses the old, working port - [example](https://pastebin.com/eCwyAfn6)

Start with the Chapter 1 source for page 6 and review the quoted SSH configuration guidance. Reproduce the behavior using the shown inventory, ~/.ssh/config, and `ansible -i inv test -m ping`, including the reported caching sequence. Done means the chapter accurately describes whether Ansible uses SSH config and explains the observed behavior.
