Handle e-mail autolinks in a safer way. For standard e-mail autolinks <user@host> we internally transformed '<' into '@' (permissive e-mail autolink) to unify handling of missing "mailto:" needed into the destination attribute. This is now not true anymore and we handle that specially. It is actually what has bitten us in https://oss-fuzz.com/testcase-detail/4815193402048512. Even though this isn't the root cause of the issue, this change makes the code safer and easier to understand.
