Wildcards are dangerous

« How to specify what to lint Output from namelint »

We consider wildcards to be very dangerous from a security standpoint. It is too easy to have something strange in a filename that causes a wildcard to not match. This made worse if there are multiple programs that evaluate wildcards: something could match in one and not in the other.

We are explicitly choosing not to support wildcards when specifying top-level paths. Ideally, you should specify the current directory (with .) and every file and directory should be included.

Additionally, we want to check every file. Even hidden and ignored files should obey basic sanity rules. Thus, we have an not-linted rule that will flag every file that doesn’t get linted.
