We could give priority to underline when there are no curly brackets,
priority to subscript otherwise. It sounds overly complicated though.

org-element.el is meant to implement _exactly_ Org syntax. Not
a superset of it.

Again, `org-use-sub-superscripts' is, at the moment, a visual-only
variable. My plan is to move it out, not in.
