Test local update following a merge checkin scenario.  A new private file is created based upon version-1.
This private file is modified resulting in a file which is shorter than a new version-3.  This new private file
prior to update contains:
		Parms: TestParm1=0x320
		Buffers: 0[-1]=empty, 1[21]=0xff.., 2[12]=0xf2..
Following update the private file should match version-3 which contains:
		Parms: TestParm1=0x329, TestParm2=0x549, TestParm2=0x679
		Buffers: 0[-1]=empty, 1[11]=0xf1.., 2[12]=0xf2.., 3[13]=0xf3.., 4[14]=empty, 5[15]=0xf5.., 6[-1]=empty, 7[17]=0xf7.., 8[18]=0xf8.., 9[19]=0xf9..
