all_whitespace	Returns `None` if the first `col` chars of `s` contain a non-whitespace char. Otherwise returns `Some(k)` where `k` is first char offset after that leading whitespace. Note that `k` may be outside bounds of `s`.
beautify_doc_string	Makes a doc string more presentable to users. Used by rustdoc and perhaps other tools, but not by rustc.
