Overview

GFM Extended autolinks: rewrites bare URLs (‘https://…`, `http://…`, `ftp://…`, `www.…`) and email addresses inside TEXT nodes into LINK nodes. Runs as an optional pass after the ordinary inline pipeline, so by then all CommonMark inline structure (real `<…>` autolinks, code spans, links, …) is already in place and protected from rewriting.
