I'm removing empty identifiers everywhere, because in practice they always mean "no identifier" rather than "empty identifier". (An empty identifier is impossible.) It's better to use `Option` to mean "no identifier" because you then can't forget about the "no identifier" possibility. Some specifics: - When testing an attribute for a single name, the commit uses the `has_name` method. - When testing an attribute for multiple names, the commit uses the new `has_any_name` method. - When using `match` on an attribute, the match arms now have `Some` on them. In the tests, we now avoid printing empty identifiers by not printing the identifier in the `error:` line at all, instead letting the carets point out the problem.
