Couldn't the svn:externals code detect when an external subdir is from
the same repository as its parent, so that
$ svn up -rN
would update both the parent and the svn:external subdir to N in that
case? And in the not-same case, it would update the parent to N and
the external to HEAD, as it does now, of course.
