# Create a revert that moves from HEAD (including any test modifications to
# the work tree) to $1 by first checking out $1 and reverting it. Reverting
# the revert is the transition we test for. We tar the current work tree
# first so we can restore the work tree test setup after doing the checkout
# and revert.  We test here that the restored work tree content is identical
# to that at the beginning. The last revert is then tested by the framework.
