cvs2svn made lots of old ports tags basically empty

[Ulrich Spörlein]

Hey folks, I need some archaeological guidance.

Some of the old ports release tags and branches are empty.

Compare empty: https://svnweb.freebsd.org/ports/tags/RELEASE_2_0/
vs. ok: https://svnweb.freebsd.org/ports/tags/RELEASE_2_2_1/

(there are also branches under tags and tags under branches, but
that's easy enough to patch up).

I don't think this is intended? For the RELEASE_2_0 (and many others),
the SVN rev looks like so:
https://svnweb.freebsd.org/ports?view=revision&revision=442

Note that it copies the root, but then deletes everything _but_ Mk. I
take it this is not what was wanted and the release tags are supposed
to ship a full tree, not just Mk?

Cheers
Uli
