AC should be able to appeal when director makes substantive changes and then approves

In the the W3C Process section 7.2, it should say:

"When Advisory Committee review immediately precedes a decision, 
Advisory Committee representatives /may/ appeal rejection of the 
proposal by the Director, and may appeal approval if  there was dissent 
<https://www.w3.org/2015/Process-20150901/#def-Dissent> or if the 
Director approved _substantive changes_ to the proposal after the review."

Section 7.1.2 says that one of the options for the Director after AC 
Review is: "The proposal is approved, possibly with substantive changes 
<https://www.w3.org/2015/Process-20150901/#substantive-change> 
integrated. In this case the Director's announcement /must/ include 
rationale for the decision to advance the document despite the proposal 
for a substantive change."

The AC should be able to appeal if what is approved is substantively 
different than what they reviewed.  Also, the AC should be able to 
appeal if the Director rejects the proposal.

(The current wording in that section appears to allow the AC to appeal a 
Director rejection of a proposal, but only if someone in the AC agreed 
with the Director about rejecting the proposal and dissented. I think 
the idea was the director would never reject any proposal because no 
proposal could ever be made unless the Director agreed ahead of time.  
But, we shouldn't count on that always being true and should be able to 
appeal a rejection.).
