branch info

[Ronald Petty]

I just reread the rcsfile man page and had the following question.  This
question might be answered if I read the source code to cvs, but I
haven't yet.  

Basically, why do you need have

branches        {num}*; 

under the delta node (grammar).

It seems to be redundant because the 

num

that is listed for the given delta has all that information (branch
points).

ex.  If the node num is 1.2.2.1
Why have 1.2.2.1 in the branch field, unless I read the man page wrong
it says that it is showing the points for which it is a branch point,
which is shown in the num field.

??  am I confused?
