+<p>Reintegrate merges now succeed in the case where all the prior 'sync'
+merges were done as subtree merges, but effectively all the changes were
+merged from the target to the source.  Reintegrate also works with shallow
+targets, as long as none of the excluded subtrees are affected by the

+<p>Merge-tracking aware merges now produce special notifications and headers
+when a merge records mergeinfo describing a merge or elides mergeinfo.  This
+clearly differentiates between changes that are made due to application of a
+diff from the merge source and those that are simply merge-tracking
+'housekeeping' changes.</p>
