Title: add dot for ngrep match expression (so tcp isn't match expression)

```
$ sudo ngrep -qd any tcp dst port 2003
interface: any
filter: (ip or ip6) and ( dst port 2003 )
match: tcp
```

versus

```
$ sudo ngrep -qd any . tcp dst port 2003
interface: any
filter: (ip or ip6) and ( tcp dst port 2003 )
match: .
```
