This defines a 'broken-revision-1-2' and a 'broken-revision-2-1' which both have their file version parents reversed compared to the revision parents, which is invalid. (We use two revisions with opposite orderings of the same parents to make sure that accidentally relying on dictionary/set ordering cannot make the test pass; the assumption is that while dict/set iteration order is arbitrary, it is also consistent within a single test).
