That sentence makes me a little dizzy.  I think you mean that since -a 
is equivalent to listing all packages on the command line, -r or -R are 
redundant.

So portupgrade \* (i.e., -a) is a superset of

portupgrade -r libexample

because all the dependencies of libexample are included in the \* and so 
portupgrade will see they need to be updated because a port they depend 
on has been updated...  Right?
