Turns out the only reason initdb -X worked is that pg_mkdir_p won't whine if you point it at something that's a symlink to a directory. Otherwise, the attempt to create pg_xlog/ just like all the other subdirectories would have failed. Let's be a little more explicit about what's happening. Oversight in my patch for bug #13853 (mea culpa for not testing -X ...)
