Applying "Assign Return Value To New Variable" to a multiline statement also indents the lines following the first line. For example, applying the hint on

    private static void example()
    {
        System.out
            .append("foo")
            .append("bar");
    }

results in:

    private static void example()
    {
        PrintStream append = System.out
                                 .append("foo")
                                 .append("bar");
    }

This is inconsistent with the usual indentation behavior (upon pressing Enter, or using Source->Format) which uses the configured Continuation Indentation Size.

I would suggest to have the hint only modify the first line, and leave the remaining lines of the statement unmodified. E.g. the result in the above example would be

    private static void example()
    {
        PrintStream append = System.out
            .append("foo")
            .append("bar");
    }

just as it would be when pressing Enter after "PrintStream append = System.out" and then typing ".append(...)".
