+ `listsinceblock` did not behave correctly when handed a block that was
+ no longer in the main chain:
+
+ ab0
+ / \
+ aa1 [tx0] bb1
+ | |
+ aa2 bb2
+ | |
+ aa3 bb3
+ |
+ bb4
+
+ Consider a client that has only seen block `aa3` above. It asks the node
+ to `listsinceblock aa3`. But at some point prior the main chain switched
+ to the bb chain.
+
+ Previously: listsinceblock would find height=4 for block aa3 and compare
+ this to height=5 for the tip of the chain (bb4). It would then return
+ results restricted to bb3-bb4.
+
+ Now: listsinceblock finds the fork at ab0 and returns results in the
+ range bb1-bb4.
+
+ This test only checks that [tx0] is present.
