Fixed bug where list instrumentation would fail to represent a
setslice of ``[0:0]`` correctly, which in particular could occur
when using ``insert(0, item)`` with the association proxy. Due
to some quirk in Python collections, the issue was much more likely
with Python 3 rather than 2. Also in 0.8.3, 0.7.11.
