The test suite flagged that git-annex info in a readonly repository was
no longer working.
.git/annex/journal.lck: openFd: permission denied
This fixes it, however, in a case where .git/annex/reposize/ is
writable, but .git/annex/journal/ is not, there will still be a
permission denied error. The solution would just be to use consistent
permissions I suppose.
