+commit 06ddae478277fba10feed6fc2eeabba686e6688a

+
+    sendRecvSnapshots - don't cut dstDataSet in-place
+    
+    The current code in sendRecvSnapshots splits the dstDataSet var
+    early on in the execution chain to provide logging output and the
+    remote variable contents. This removes the remote information from
+    dstDataSet which is then passed to listSnapshots without the
+    remote data and the attempt to list the last snapshot occurs on the
+    local host, not over SSH on the remote target.
+    
+    Address the issue by creating a dstDataSetPath variable to hold the
+    stripped target path while retaining the original dstDataSet with
+    the remote information attached for lastAndCommonSnapshots to use
+    in listSnapshots.
