        Yes, this is exactly how I wanted it to work. It's wonderful when your
mental model actually matches reality ...

        I was somewhat confused by the subversion book, which (at least in my
slightly old version) mentions switch only in the context of updating to the
tip of the branch --- there's no mention of merging in WC changes. And since
I haven't managed to compile subversion yet, I haven't actually been able to
try it out.

        Anyway, thanks for the information --- you just made my evening.
