Wishlist: quick fix for "possible incorrect indentation"

#### Repro steps

Have this code:

```fsharp

let foo = match [1] with
| _ -> ()
```

You get squigglies for |, with the tip:

_Possible incorrect indentation: this token is offside of context started at position (119:15). Try indenting this token further or using standard formatting conventions."_

We could have an autofix to indent this correctly, yielding code:
```fsharp
let foo = match [1] with
| _ -> ()
```

As a bonus, pressing "tab" on the second line could stop at the minimum correct indentation. Currently,
you need to press space N times to hit the exact spot.
