Merge branch 'nd/submodule-pathspec-ending-with-slash'

Allow "git cmd path/", when the 'path' is where a submodule is bound to the top-level working tree, to match 'path', despite the extra and unnecessary trailing slash. * nd/submodule-pathspec-ending-with-slash: clean: use cache_name_is_other() clean: replace match_pathspec() with dir_path_match() pathspec: pass directory indicator to match_pathspec_item() match_pathspec: match pathspec "foo/" against directory "foo" dir.c: prepare match_pathspec_item for taking more flags pathspec: rename match_pathspec_depth() to match_pathspec() pathspec: convert some match_pathspec_depth() to dir_path_match() pathspec: convert some match_pathspec_depth() to ce_path_match()
