Revert "test-wildmatch: add "perf" command to compare wildmatch and fnmatch"
This reverts commit 1b25892636d2f250eb2163301440ee8c8c1ac944. compat fnmatch will be removed soon and we can't rely on fnmatch() available everywhere. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
