Changed rewrite rules look weird 

After changing the state config I ran `wp dictator compare site-state.yml` and got this:

```
- permalink_structure: /ear%/onthnum%/%day%/ostname%/
+ permalink_structure: /onthnum%/%day%/ostname%/
```

Notice the missing `%first-letter` for `%y`, `%m`, `%p` but not for `%d`...
