Short implementations of functional interfaces could be on a single line

[bethcutler]

Actual:

fun interface VeryVeryLongCustomInterface {
  fun function(options: Options): EndResult
}

val EMPTY_VERY_VERY_LONG_CUSTOM_INTERFACE: VeryVeryLongCustomInterface =
    VeryVeryLongCustomInterface {
  EndResult
}

Preferable, perhaps?

val EMPTY_VERY_VERY_LONG_CUSTOM_INTERFACE: VeryVeryLongCustomInterface =
    VeryVeryLongCustomInterface { EndResult }

I think this is the same as #252.

BTW this happens because of the line break. If there were no line breaks it would be placed on a single line

val EMPTY: VeryVeryLongCustomInterface = VeryVeryLongCustomInterface { EndResult }
