…steffen new lint: `recursive_format_impl` The to_string_in_display lint is renamed to recursive_format_impl A check is added for the use of self formatted with Display or Debug inside any format string in the same impl The to_string_in_display check is kept as is - like in the format_in_format_args lint This is my first contribution so please check it for better / more idiomatic checks + error messages. Note the format macro paths are shared with the `format_in_format_args` lint - maybe those could be moved to clippy utils too. This relates to issues rust-lang#2691 and rust-lang#7830 ------ changelog: Renamed `to_string_in_display` lint to [`recursive_format_impl`] with new check for any use of self as Display or Debug inside the same format trait impl.
