t4008: modernise style
Update this ancient test script to a more modern style in which the expected result is prepared inside the body of the test that uses it. Also, instead of using $tree, a shell variable, throughout the test script, create a tag that points at it, to make it easier to manually debug the test script in its trash directory.
