In moveBatch.php's comments, mention it will give
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.
