In moveBatch.php's comments, mention it will give FAILED: immobile_namespace for Category*: namespace, and perhaps some others. That way we can be mentally prepared, for goodness sakes. Else we have to clean up after a half processed job.
Comments cleaned up in r18587. I noted that error codes come from Title::moveTo(), which will help with searching for the meaning of a particular code, and I gave an example.
