test-convert: demonstrate an unstable hash issue for bzr -> hg -> hg
It looks like the manifest value changing is the only difference, but I'm not
sure why it's happening. I've got a similar divergence in a production repo
that was also converted from bzr and has an octopus merge[1]. Unlike here, the
manifest values for the destination merge commits reflect the initial merge
only, instead of all four merges agreeing like this test.
$ hg -R src_repo manifest -r 310 --debug | grep file # octopus fixup merge

$ hg -R src_repo manifest -r 309 --debug | grep file # first merge

$ hg -R dst_repo manifest -r 272 --debug | grep file # first merge

This divergence is espcially annoying because unlike changelog differences, I
haven't figured out a way to fix this in code. The only way I found to work
around it is to convert up to the point of divergence, `hg bundle` the bad
revision in the source, apply it to the destination, add a line to the shamap,
and fire off the conversion again.
But I suspect that there's more to it than just the octopus merge because
I also have a commit in the same repo, done in Mercurial (well after the
conversion) that is exhibiting a similar issue (and it's not a merge commit).
I'm almost positive that it was created with 4.4 or later. Any ideas?
