 * follow a word character, so an email address mentions no one. Nor may it
 * follow `[` or `(`, which leaves out a Markdown link's text or URL starting
 * with `@`, and also a plain `(@name)`.
 * `notifyMentions` notifies the users it matches, and the chat's
 * `mentionsUser` highlights and chimes by it. `Markdown` links mentions with a
 * looser pattern of its own, on text already parsed.
