Due to a problem with ripper we do not recognize `break` as invalid code. It's confusing that "Syntax OK" is output in that case.

When there's no syntax error, the algorithm should not say anything. The exception is in the CLI and that's for compatibility with `ruby -wc`

```
$ cat /tmp/break.rb
break
⛄ 3.1.2 🚀 /Users/rschneeman/Documents/projects/syntax_suggest (schneems/no-syntax-not-okay-break)
$ ruby -wc /tmp/break.rb
Syntax OK
```

> Note that this is invalid, running this code will raise a Syntax error.

```
$ exe/syntax_suggest /tmp/break.rb
Syntax OK
```
