e.g.
-->%--->%--->%--->%--

int test(int i)
{//<-- show this line

//lot of code...

}//<-- cursor

-->%--->%--->%--->%--

It would be better if it show two lines not only one without any informations.
In some corner cases it would not work but for 99% will be fine.

e.g.
-->%--->%--->%--->%--

W::W() :
    _a(), _b() //it will show only this, but at lest you can deduce what `{` it is
{

//lot of code...

}//<-- cursor
