> multi-wc-format/BRANCH-README mentioned this:
> > [*] New externals working copies must inherit the format from their
> > parent working copy, because mixed-format working copies are a) a
> > Bad Thing, and b) defeat the purpose of this feature, which is

> Upgrading a parent working copy upgrades external wc's too. However,
> upgrading an external succeeds. Judging by the quoted remark, should
> «svn upgrade --compatible-version=$N /path/to/external» error out unless
> the external's parent working copy is already at version $V?
