test-rename-merge2: make selected output less arbitrary It's unclear why everything from the first 'updating:' line should be ignored. The arbitrariness makes it confusing that changing the code so e.g. the 'getting 8/f' line is printed later makes it disappear completely from the ouput. The list of 'preserving x for resolve of y' seems convered by the subsequent for loop in the test case. Perhaps it's only copies that are of interests, so let's keep only that part.
