Thanks for this. Right up to here, I thought it was going to be hard ..

It could be made a bit smarter in finding the latest svnup update, when
updating to a release or releng rather than stable, but that's icing.
[Oddly, I found an old version of svn installed from early 2013, that a)
pkg2ng hadn't found because b) it had no old /var/db/svn* directory, ie
was unregistered. Before removal, svnversion /usr/src said 'Unversioned
directory', which was true enough.]
