tests: demonstrate a problem with renames on the p2 side of a conversion I think this is related to the octopus merge being sloppy, and that's having a cascading affect on the fixup merge. If this change is made on p1 (specifically with the 'Added parent file' commit), the failure doesn't occur. The file modification with the rename doesn't seem to be necessary, but it's what's happening in a production repo where I first noticed, so I left it. This is an example of the manifest divergence I'd been seeing, which wasn't fixed by Yuya's recent changes. This is separate from the changelog divergence I was also seeing[1]. Probably nobody cares about bzr anymore, but this will also affect git, since the octopus fixup code is in the hg sink.

In the merge below, the file "foo" has the same contents in both
parents, but if we look at the file-level history, we'll notice that
the version in p1 is an ancestor of the version in p2. This test makes
sure that we'll use the version from p2 in the manifest of the merge
revision.
