It appears like the plugin doesn't like the exclamation mark to force-unescape HTML. I tried running it on a large code base, and it broke a lot of templates because it removes all the exclamation marks. While explicitly calling .html_safe is a "workaround", I'm not sure if the reformatting should remove the exclamation marks - after all, that's a very explicit decision a well. :)
