PROTON-116: avoid sending redundant disposition frames
> Proton sends explicit disposition for pre-settled messages
> ----------------------------------------------------------
>
> Key: PROTON-116
> URL: https://issues.apache.org/jira/browse/PROTON-116
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.2
> Reporter: Ted Ross
> Priority: Minor
> Fix For: 0.5
>
>
> When proton sends pre-settled messages (the settled flag is set in the
> transfer), it follows up with an explicit disposition frame for the message.
> I believe this disposition update is spurious and unneeded, though I haven't
> found a definitive statement one way or the other in the protocol
> specification.
