In cone mode, the sparse-checkout commmand will write patterns that allow faster pattern matching. This matching only works if the patterns in the sparse-checkout file are those written by that command. Users can edit the sparse-checkout file and create patterns that cause the cone mode matching to fail. The cone mode patterns may end in "/*" but otherwise an un-escaped asterisk or other glob character is invalid. Add checks to disable cone mode when seeing these values. A later change will properly handle escaped globs. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
