 * The bag lists each dest's values in occurrence order and the dests
 * themselves in first-typed order, so the rebuilt list is exact unless
 * a line alternates the two kinds three or more times (`--include a
 * --exclude b --include c`), where each kind's rules stay grouped at

 * GNU's --include/--exclude gate for one candidate file.
 *
 * Globs match the base name with fnmatch wildcards, case sensitively (a
 * glob carrying a slash therefore matches nothing, which is what GNU
 * 3.11 answers too). The rules resolve in command-line order: the last
 * matching rule decides, and a file matching none is admitted only when the
 * first rule is an exclude (both pinned against GNU 3.11, where
 * `--include='*.txt' --exclude='*.txt'` skips a .txt file and the reversed
 * order searches it). Applies to command-line files exactly as to walked
 * ones, which is pinned GNU behavior: an explicit operand --include passes
 * over is silently no match, not an error.
