Trigger a linter once without passing files?

Hello, and thanks for a great project!

I’d like to use lint-staged to run the flow typechecker if a commit would contain .js files. flow does not expect to be passed individual files, and does not need to run once per file; instead, no matter how many .js files are in the commit, flow only needs to run once.

I saw #174 - the reason I would like to use lint-staged is because I have other linters (stylelint, eslint) that should also run. Currently, I’m getting this to work with the following config:

{
  "scripts": {
    "precommit": "lint-staged && flow"
  },
  "lint-staged": {
    "*.css": "stylelint",
    "*.scss": "stylelint --syntax=scss",
    "*.js": "eslint"
  }
}

but this makes flow run after all linters, instead of potentially letting it run in parallel. It also feels cleaner to have “precommit” just be “lint-staged”, instead of a shell-chained list of commands.

BTW when #138 is done it should be possible to run commands without arguments.

For people landing here, this is now possible with functions as linter commands: https://github.com/okonet/lint-staged#using-js-functions-to-customize-linter-commands
