> Breaking the line of too long statements (line longness is yet to be fully defined) to improve code readability in case of
>  * Long function argument lists (declaration or call): void func(type1 arg1, type2 arg2, ...)
>  * Long sequence of chained calls: list.stream().map(...).reduce(...).collect(...)...
> Rules:
>  * Break the list of arguments/calls if the line exceeds limit or earlier if you believe that the breaking would improve the code readability
>  * If you break the line then each argument/call should have a separate line, including the first one
>  * Each new line argument/call should have one extra indentation relative to the line of the parent function name or called entity
>  * The opening parenthesis always stays on the line of the parent function name
>  * The possible thrown exception list is never broken and stays on the same last line
>  * The dot of a chained call is always on the line of that chained call proceeding the call at the beginning
> Examples of breaking:
>  * Function arguments
> {code:java}
> public void func(
>     int arg1,
>     int arg2,
>     ...) throws E1, E2, E3 {
>     
> }{code}
>  * Chained method calls:
> {code:java}
> values
>     .stream()
>     .map(...)
>     .collect(...);{code}
