path_auditor: cache names of audited directories We use a separate cache to avoid problems with audit = path_auditor(repo.root) audit("subrepo") audit("subrepo/file") whitelisting "subrepo" (which is fine) and then using the same whitelist with "subrepo/file" (which is not fine). Since we create a separate path_auditor for every path on the command line, a "hg add dir/a dir/b dir/c" will still lstat dir 3 times just to audit the paths.
