it seems that `git-annex` sometimes does commits with empty commit messages. this makes rebasing git-annex branches much much harder than they need to, because rebase freaks out on those weird commits:
anarcat@marcos:video$ git rebase --continue Waiting for Emacs... Aborting commit due to empty commit message. Could not commit staged changes.This was trying to fix [[a broken merge|forum/canceling_wrong_repository_merge/]]... --[[anarcat]]
