Linkify Fediverse links properly
I've noticed that Tildes autolinks any string that looks like an e-mail address, which is a good idea, but breaks down for Fediverse identities; for example, @tindall@cybre.space, an ActivityPub Actor on the server cybre.space, is presented as an @ sign followed by the email address tindall@cybre.space. It would probably be better if this didn't highlight at all, or actually linked to that actor (https://cybre.space/@tindall).
