You claim you did not cut it off before the end of the sentence?

I'll agree that "restatement" might be the wrong way of
expressing this idea.
Arguments that "that is to say" does not introduce a restatement
are not arguments that the definition is complete without that
clause.
For the moment, I'm going to simply point out that wordnet
indicates that "that is to say" means basically the same thing
as "namely", and that a google define: search on that phrase
points me at wordnet.

This idea pervades the copyright system. For example, 17 USC 102:
The historic expansion of copyright has also applied to forms of expression
which, although in existence for generations or centuries, have
only gradually
come to be recognized as creative and worthy of protection.
For example, the berne convention says, in Article 2:
(5) Collections of literary or artistic works such as encyclopaedias and
anthologies which, by reason of the selection and arrangement of their
contents, constitute intellectual creations shall be protected as such,
without prejudice to the copyright in each of the works forming part of
such collections.
It's very clear that what copyright is protecting is not the symbols which
comprise a document but the creative content that they represent.

I've not studied these, but they're both superman stories, right?
Are you saying that these did not share creative content?
(Even if that were the case, the copyright on other issues
of Action Comics is likely significant.)

Sure, among other things you've got Linus being responsible for
both and having supervised the intermediate versions (which had
stronger creative ties to each other). And, of course, the copyright
is on the kernel as a whole -- sections taken in isolation are
copyrighted as a part of the whole.

I'm sorry, I didn't express the idea well enough. My point was that
copyright law does not place additional restrictions on your distribution
of the GPLed program which are specific to these collective works
which are not being protected as intellectual creations.
And, if you allow the full definition of a "work based on the Program"
from section 0 of the GPL to apply, it's clear that when these
collective works are being protected as intellectual creations that
you're talking about a "work based on the Program" and so can
be granted license by the GPL.
