Unusual Record Formatting (hard tabs)

In the example

```
data Customer = Customer {
customerID :: CustomerID,
customerName :: String,
customerAddress :: Address
} deriving Show
```

stylish yields

```
data Customer = Customer {
customerID :: Cust omerID,
customerName :: Stri ng,
customerAddress :: Address
} deriving Show
```

In Utrecht style

```
data Customer = Customer {
customerID :: CustomerID
, customerName :: String
, customerAddress :: Address
} deriving Show
```

stylish yields

```
data Customer = Customer {
customerID :: Cust omerID
, customerName :: Stri ng
, customerAddress :: Address
} deriving Show
```

My global config contains

```
- records: {}
```

It appears that this is only an issue when using hard tabs. Using soft tabs yields the expected results. While this is more correct w.r.t. the Report, it may be worthwhile to add support for tabs, or provide a warning in the README about this case.
