Savannah bug #23920: warn about -path arguments ending in /. * find/parser.c (insert_path_check): new function; abstracts the common functionality of parse_path, parse_ipath, parse_wholename, parse_iwholename. Also check for a trailing slash and warn about it (unless $POSIXLY_CORRECT is set). Don't warn if the pattern also happens to be a start_point, because those could be matched. (parse_path, parse_ipath, parse_wholename, parse_iwholename): Use insert_path_check. * find/tree.c (is_start_point): new function; returns true if the indidated string matches a start point. (num_start_points, start_points): new variables, storing the starting points listed on the command line. (build_expression_tree): Set num_start_points and start_points. * find/defs.h: Declare is_start_point. * doc/find.texi (Full Name Patterns): Explain that candidate names for -path, -regex etc. will never end in a slash, so "-path /tmp/" will never match anything. * find/find.1: Likewise.
