/**
 * The subtree listing tar and zip both walk with.
 *
 * Reuses find's walk so an archiver classifies an entry exactly the way find
 * does (through stat, never by name). The two calls a directory operand makes
 * share one readdir cache, so the second is answered from the index instead of
 * the backend.
 *
 * walkFind stands in for a backend's native find op, so it answers in
 * mount-relative keys; both archivers name members from virtual paths, so they
 * are lifted back here the way findGeneric lifts them. A directory the walk
 * could not open rides along (as the virtual path the walk recorded), so the
 * archiver can report it the way GNU does instead of silently leaving its
 * contents out.
