A number of edit relationship type edits are completely blank where they should show the changes.
In review at https://github.com/metabrainz/musicbrainz-server/pull/20
I missed a property (child order) in my initial patch, which I've added in now. The final two edits in the list in the ticket description don't have any changes, so these still appear empty.
They shouldn't be empty:
http://classic.musicbrainz.org/show/edit/index.html?editid=4396935 changed the instrument attribute from 0-1 to 0-n
http://classic.musicbrainz.org/show/edit/index.html?editid=12315864 added the assistant and associate attributes
