This commit partially reverts rust-lang#3934, opting to create a span that covers the entire body of a closure when formatting a closure body with a block-formatting strategy, rather than having the block-formatting code determine if the visitor pointer should be rewound. The problem with rewinding the visitor pointer is it may be incorrect for other (i.e. non-artificial) AST nodes, as in the case of rust-lang#4382. Closes rust-lang#4382
