When a string is concatenated on multiple lines inside a closure, the indentation is wrong on the second line if the first line contains a concatenating dot:

<?php
someClosureHandling(
    function () {
        return 'a' . 'b'
                   . 'c';
    }
);

. 'c'; should be indented 4 characters relative to return, and not on the same position as the dot in the line above.

Should be:

<?php
someClosureHandling(
    function () {
        return 'a' . 'b'
            . 'c';
    }
);
