I'm not quite sure whether I understand why this problem is
tricky to solve. Monotone versions prior to 0.21 behaved exactly
the way I need it: Issue a warning, go on synchronizing those
branches that haven't been excluded. The new release is the first
one to abort the connection entirely in case a branch has been
excluded.

I'm willing to live with that. The number of branches I exclude
is small, I doubt the performance penality would be noticeable.

Now I am confused. Why would I use Monotone if I _hadn't_ lots of
different servers? If I had only one, I'd be using Subversion,
right? ;-)
