No debug output with `-v` in interpreter mode

I would like to see what `stack` is doing when it's running a script but it currently refuses:

Take `turtle.hs`:

```
#!/usr/bin/env stack
-- stack -v --resolver lts-6.6 --install-ghc runghc --package turtle

{-# LANGUAGE OverloadedStrings #-}
import Turtle
main = echo "Hello World!"
```

```
~ $ ./turtle.hs
~ $ ./turtle.hs
Completed 5 action(s).
Hello World!
```

`stack -v turtle.hs` isn't even valid syntax:

```
~ $ stack -v turtle.hs
Invalid argument `turtle.hs'
File does not exist or is not a regular file `-v'

```

Is there a reason why we can't override script options by passing them to `stack script`?
