[feature request]run lerna script against staged-files

I would like to run lerna scripts against packages that have staged files. It similar to --since flag. I would recommend to add new filtered flag --staged (git diff --cached).

Expected Behavior

Run pre-commit git hook with husky using lint-staged package on packages that have staged files. The command should looks like: lerna run pre-commit --staged

Current Behavior

There is not such possibility yet

The proposed --since HEAD solution will run the command on every package with changed files not staged ones. Could this be reopened and the feature request reconsidered?

For the exact same use case, I was able to use lerna run pre-commit --since HEAD.

You would place that in your root package.json config.

  "husky": {
    "hooks": {
      "pre-commit": "lerna run pre-commit --concurrency 1 --since HEAD"
    }
  }

This will only run the pre-commit script on packages that have staged changes within them.
