This breaks the usecase of tagging trunk by just copying it. And it  
would
be impossible to check out a single package with "svn co". The testing
is a transient process and I would prefer to then introduce some  
script like
   setgar current/v2-testfeature pkg/*/trunk
which would just reset links to the specified one without touching the  
svn:externals.
