Description
Submitting a change with no comment and no change to the data shows a message with a "Go back" link to the referrer. A browser that sends no referrer got a server error instead of the message. The message now appears, and in that case its link goes to the edit page of the change.
Testing
apps/oi/tests/test_submit_empty_change.pysubmits such a change with and without a referrer and checks the link. Without the change the case with no referrer fails withKeyError: 'HTTP_REFERER'. Full suite: 1010 passed, 0 failed.
