I think this is OK. I had originally thought we should return whatever XR_*
code get_sb() returned, but I wasn't thinking straight; we ignore those
other codes, and only stop if we see XR_EOF.
So this is fine as far as it goes; I noticed something else in the process
though so I'll send a patch for that. :)
