ring-insert, pcl-cvs, and vc-cc

Previously, Adrian mentioned the problem with ring-insert and pcl-cvs v2_9_9 where pcl-cvs was calling (ring-insert vc-comment-ring <string>) but vc-comment-ring was nil. I didn't see any patch or comments in the mail archives so here is my patch. Without it, I can't commit anything with pcl-cvs. It's a bug in vc-cc/vc.el for not initializing vc-comment-ring to a ring.
