The enumeration dropped every `!` line and matched with fnmatch, whose `*` crosses
`/`. YesWiki's `tools/*` followed by `!tools/bazar` therefore removed all 583 PHP
files under tools/, the vulnerable FormManager.php among them. The scan read 243 of
803 files, completed 1128 of 1128 questions and looked clean: a zero from an unread
tree.
Rules now follow git:
- the last matching rule wins, and `!` re-includes;
- `*` and `?` stay inside one path component, and `**` crosses components;
- a rule with an inner `/` is anchored to the root;
- a trailing `/` matches directories only;
- nothing under an ignored directory can be re-included.
In a work tree, a tracked file is never ignored, because `.gitignore` describes what
the repository does not hold.
The test uses `git check-ignore` as the oracle on 16 paths covering negation,
anchoring, depth, directory-only and `**`. It also covers a git-archive export with
no .git, and a tracked file under an ignored directory. All three tests fail on the
old reader.
