You're right; this approach assumes that at any particular time there would
be one and only one useful URL for the same repo.

You make a strong case, as usual. :-)

That WC usage model is certainly space-inefficient, but hey, it's your
disk, you can use it how you please. :-)

All I can say is that losing this functionality (you'd have to, instead,
tweak your config file) is, IMO, preferable to having a potentially-wrong
URL all over the WC.

There is a middle-ground solution: continue to support the url= (or, in
light of issue-960, repos=) WC entry, but fall back to a UUID-based lookup
when none is present. An additional subcommand, "svn bind", could attach
the WC to a particular, preferred URL, and "svn bind -u" could detach it.
