Well, I personally keep the TRUNK and any branches I need checked out all
the time (as opposed to trying to switch a single sandbox from branch to
trunk and back). So, for me, doing a diff on the TRUNK is a simple matter
of merely changing over to my TRUNK folder and doing the diff. That's what
I was really suggesting. Though, like you said, if you don't already have a
copy of the TRUNK checked out, then you would have to do that. But once
done, it's done, and you just have to make sure it is up to date before
doing a diff like we're talking about.
I agree that it is too bad that "HEAD" does not refer to the top of the
TRUNK when you're working on a branch. I think there was some discussion
some time ago about the idea of introducing a new keyword (like "TOP" or
"TIP" or something like that) that would always refer to the current
revision on the TRUNK regardless of where you are currently working, but I
don't know what came of it.

It is my understanding that HEAD always refers to the latest revision on the
branch you are working in. So, if you are in the TRUNK, then it is the head
of the trunk. If you are in a branch, then it is the head of the branch.
In other words, "HEAD" is relative to your current location. Also, if you
are up to date on the branch/trunk, you don't even need to use "HEAD". You
can just say, "cvs diff -r <tag>" and that will give you the differences
between the tag and the current head (because "HEAD" is redundant if your
local sandbox is up to date).
I've never needed to use "HEAD" myself, so I could be mistaken; but I
believe I understand its use correctly.
