This is the same as the patches I sent last Friday, but split better
and without the extraneous change to the seabios submodule.

v1->v2: rearranged patches more coherently

Paolo Bonzini (3):
  add some tests for invalid JSON
  implement optional lookahead in json lexer
  remove unnecessary lookaheads

Not requiring one extra character when lookahead is not necessary
ensures that clients behave properly even if they, for example,
send QMP requests without a trailing newline.

I think this series conflicts a bit with Luiz's series which I just

You didn't apply this one yet, at least I don't see it on qemu.git

commit e546343ee0f3f904529d32c1a9a60f5baa181852
Author: Luiz Capitulino <lcapitulino@redhat.com>
Date:   Wed May 19 18:15:32 2010 -0300

     json-lexer: Drop 'buf'

     QString supports adding a single char, 'buf' is unneeded.

     Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

I based my series on top of Luiz's, so it should apply.  The above is 
the only commit that is actually required.  I can ping the series once 
Luiz's patches are applied, so you can disregard it in the meanwhile.

Yeah, I confused myself into thinking that Luiz's series was more 
contentious than it is.  Nevermind, your patches are fine on top of his.
