I think we can at least include one basic test. Also, as it turns out
the problem I was seeing _wasn't_ the same one Jonathan fixed. There's
another bug. :)

So here's a patch series that fixes my bug, and then a cut-down version
of Jonathan's patch. I'd be happy to see more tests come on top. I don't
think there's a huge rush on getting any of this into master. There are
bugs in the existing code, but they're very hard to trigger in practice
(e.g., a non-repo which happens to have a bunch of repo-like files). It
only becomes an issue in 'next' when we die("BUG") to flush these cases
out.
