Collapse lambdas vs One-line functions

[cpriest]

I'm not sure if this is a bug or a feature request:

• I have collapse lambdas checked
• I have one-line functions unchecked (though I'm not sure if that's from PHPFoldings or PhpStorm).

I've got this lambda:

	function(AMQPMessage $Message) {
		$this->onMessage($Message);
	}

Which folds to this:

(AMQPMessage $Message) -> {...}

What I'd like is this:

(AMQPMessage $Message) -> {
	$this->onMessage($Message);
}
