Hey, alright! feedback!

        [smc]  Hmm.  Ok,   And plain, unpatched CVS 1.11 behaves 
        in the same way when I tried it.  (as you say, regardless of 
        whether a magic tag is specified)  I'm not sure I understand 
        the significance of a tag existing in val-tags but not in the file.

        What does that mean?  What *should* it do in this case?  
        should  "val-tags_only_tag" behave differently than 
        "val-tags_only_tag.origin" or "val-tags_only_tag.trunk"?

        [smc]  Yeah, that's less than ideal, I suppose.  I can look into 
        trying to do something better there.

        So, perhaps the best thing to do is to say that ".trunk.origin"
        just doesn't make any sense and reject it early on. I can look 
        into making it do that, if that's preferable.

        However, I've fallen off the internet at home, I'm in the
        process of switching ISPs, and currently have no ISP.

        At work, I'm behind a firewall, plus too busy anyway.
        So, it might take a few days before I'm back in business,
