+`--reply-to` creates a new flat Jira comment containing a real mention of the
+original author and a focused-comment link. It does not quote or duplicate the
+original comment. For manually authored bodies, use Markdown links
+`[label](https://example.com)` and real mentions `@[Display Name]` or
+`@[id:accountId]`. Jira wiki links `[label|url]` remain literal, and plain
+`@Display Name` does not notify the user.
