How do you use point.case correctly?

[romanstetsyk]

With the config file like this:

ls:
  .css: point.case

The rule in it doesn't match any file that uses point case and ends with .css. For example, it won't match test.point.case.css because the extension here is point.case.css. As a consequence, it won't catch an error if there's a typo, e.g. test-point.case.css
