I agree that {} makes it look more complete, but fwiw, I think what's
needed is a way to make it complete....   Maybe this should be a new
ISSUE.    I can see reasons one might want both, but it's easy to go
from complete to incomplete with a subgraph relation, and I'm not sure
how to go from incomplete to complete.  I guess with pointing to the
file you got it from, which seems much trickier.

That is, if I need to say that G1 is exactly <s> <p> <o> and G2 contains
<s> <p> <o> and maybe some other triples, I can easily say:

(making up two new syntaxes for clarity...)

   G1 @isGraph { <s> <p> <o> }.
   G2 subGraph G1.

but it seems trickier to say:

   G2 @hasTriples { <s> <p> <o> }.
   G1 .... something about G2 and this file...?

I also like the @graph syntax as being more turtle-ish, but I worry
about this aspect of it.
