Perhaps someone from cvs_at_ can comment on this.  I assume there is a
standard approach taken for FreeBSD and it would be great if someone could
share this and that could go into the cvs users guide.  I personally
always delete files on the vendor branch if they are not off of it to
avoid creating new conflicts.  But I'm unsure where my personal
preferences end and where FreeBSD's approach begins.
