From: Derrick Stolee <dstolee@xxxxxxxxxxxxx> The final index compatibility macro to remove from the update-index builtin is ce_match_stat(). Further, this is the last use of that macro anywhere, so it should be removed. There are some remaining references in the racy-git.txt technical document that are updated to ie_match_stat().
