I don't think a hierarchy is defined in any useful way.  Tag -b (not
rtag) branches off of whatever revisions you have checked out in your
working copy.  I could have a mix of HEAD and 6.8-release and whatever
else I wanted as the base of my new branch.  One example would be that
the default branch for most of xc/extras/Mesa is the vendor branch
(MESA, revisions 1.1.1.*), while much of the rest of the tree is the
head (no branch, revisions 1.*), with the exception of files still on
the XFree86 vendor branch (XFree86, also revisions 1.1.1.*).  Tagging a
new branch like 6.8 will take a lot of files files from head, but also
the latest MESA or XFree86 vendor-branch revisions for those files that
haven't been modified in x.org CVS.

Now, I bet someone could write a nifty tool to approximate a hierarchy,
but it's not as simple as it would seem from the common-case usage.
