Comment:

 I've merged together jsgf's changes with amiller's fixes, and added a
 couple of new tests. I also fixed the implementation to not use an etag
 for t=info or t=rename-form, since both actually provide variable output.
 "", "json", "uri", "readonly-uri" are all eligible.

 I'll push the changes in a moment.
