Thanks, it seems to be working correctly now.

I'm not sure what happened.  I thought I updated and had this change
in addition to your previous one, but then I pulled again and there
were no new changesets, but updating changed 7 files.  I guess I
didn't update after my last pull.  Oops.  Sorry for the noise.
