Add test-scrap-cache-tree
A simple utility that invalidates all existing cache-tree data. We need this for tests. (We don't need a tool to rebuild the cache-tree data; git read-tree HEAD works for that.) Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
