The new turtle-subm-26.nt matches the output of serdi exactly.

However turtle-subm-06.nt and turtle-subm-08.nt still do not (the
required changes were also in my earlier patches).  For inline blank
objects, to be able to do streaming+abbreviating the statement with that
as an object *before* it emits the following statements using it as a
subject, i.e. the statement order exactly as they are encountered in the
input.

Otherwise, if you attempt to re-serialize those triples as abbreviated
Turtle, you don't have the first statement at the time you need it, i.e.
it is impossible to reconstruct the Turtle input from the output in
constant space.  This can be very important when files get very large.

Not a big deal for me, but the order of these would have to be fixed if
my implementation (or any streaming+abbreviating implementation) is to
pass the test suite exactly without modification, which would be nice.

Thanks,
