python rrdtool fetch returning one extra row

[human]

$ rrdtool create test.rrd DS:x:GAUGE:1:U:U RRA:AVERAGE:0.0:1:3 -s 1 -b 1000000000 $ rrdtool update test.rrd 1000000001:1 1000000002:2 1000000003:3 $ rrdtool fetch test.rrd AVERAGE -s 1000000000 -e 1000000003

1000000001: 1.0000000000e+00 1000000002: 2.0000000000e+00 1000000003: 3.0000000000e+00 1000000004: nan $ python

rrdtool.fetch('test.rrd', 'AVERAGE', '-s 1000000000', '-e 1000000003')

((1000000000, 1000000004, 1), ('x',), [(1.0,), (2.0,), (3.0,), (None,), (1.0185579799004822e-312,)])

rrdtool.fetch is returning an extra, bogus, data point. Attached is a patch to correct this.

This time, the issue really is in trunk and 1.2.
