Rule: equals sign should be on same line

[MyDogTom]

I would like to enforce this rule

When a property initializer does not fit on a single line, break after the equals sign (=) and use a continuation indent.

Source

Valid example

private val defaultCharset: Charset? =
        EncodingRegistry.getInstance().getDefaultCharsetForPropertiesFiles(file)

Violation example

private val defaultCharset: Charset?
        = EncodingRegistry.getInstance().getDefaultCharsetForPropertiesFiles(file)

I also would like to use same rule with functions.

Valid example

fun sum(a: Int, b: Int) = 
        a + b

Violation example

fun sum(a: Int, b: Int) 
        = a + b

PS. I'm happy to try implement it, if such PR is welcome.

Hi @MyDogTom. Absolutely. I'm kinda surprised it's not enforced yet so PR is definitely more than welcome.
