Josh Rosen commented on SPARK-3854:
-----------------------------------

Does anyone know whether we're now enforcing this?  [~rxin] may have fixed this 
recently.

> Scala style: require spaces before `{`

> We should require spaces before opening curly braces.  This isn't in the 
> style guide, but it probably should be:
> {code}
> // Correct:
> if (true) {
>   println("Wow!")
> }
> // Incorrect:
> if (true){
>    println("Wow!")
> }
> {code}
> See https://github.com/apache/spark/pull/1658#discussion-diff-18611791 for an 
> example "in the wild."
> {{git grep "){"}} shows only a few occurrences of this style.
