[MERGE] Fix bug 360791 by not raising an error when a smart server is asked for more content than it has locally; the client is assumed to be monitoring what it gets.

Comment:
+* The smart server will no longer raise 'NoSuchRevision' when streaming
+  content with a size mismatch in a reconstructed graph search: it 
assumes
+  that the client will make sure it is happy with what it got, and this
+  sort of mismatch is normal for stacked environments.

Could you add some more of the reasoning from your cover letter into the 
NEWS item here please?
