[Haxe4] Auto-indent wrong after `final` keyword

[gene-pavlovsky]

Haxe code sample

	function foo()
		if (true)
		{
			final i = 1;
			|
		}

Note: "|" is the caret position.

Start typing at the caret position, the code is auto-indented at the same level as function.
If final i is replaced with var i then indentation is correct. I guess it's related to the final keyword used in this context.
