Doesn't properly handle quoted single line strings with &"${env:foo}" and trailing }

I think you need to change your regex so that it's not as greedy.

This blows up the formatting

``` powershell
function subl { &"${Env:ProgramFiles}\Sublime Text 2\sublime_text.exe" $args }
```

If I put the ending `}` on a newline, we're all good

``` powershell
function subl { &"${Env:ProgramFiles}\Sublime Text 2\sublime_text.exe" $args 
}
```
