Nguyễn Thái Ngọc DuyBack in history, ce_path_match() was first introduced in commit fdee7d07ba6c79b3e5125e96adbe1d9c3e75ce1d, in diff-cache.c. It seems to be used to handle pathspec that we have today. But it did not support wildcards.
About one year later, match_pathspec() was introduced as match() in commit 0d78153952e70c21e94dc6b7eefcb2ac5337a902, builtin-add.c. This version supported wildcards.
For some reasons diff code did not get converted to use match_pathspec(). So diff commands do not understand wildcards. I was not here that time to know the reasons. But I find it quite handy to do "git diff -- '*.sh'", just like the rest of git commands.
Hence this patch, which simply calls match_pathspec() inside ce_path_match(). With this, "git diff-files" and "git diff-index" now support wildcards. "git diff-tree" does not because it does not use ce_path_match().
"git update-index --again" is also affected (in a good way hopefully)
