Add FILES env variable

[Simx303]

FILES environment variable will be available for scripts by adding $FILES to their script.
It will list all staged files for commit.

Here is an example:

STAGED
---
coolapp/
├─ .editorconfig +
├─ README.md
├─ src/
│  ├─ main.js +
│  ├─ utils.js +


> echo $FILES
.editorconfig src/main.js src/utils.js

> npx do-something $FILES
...

echo "$FILES" | xargs git add at the end will add again the changed files for commit.

Hello, thanks for the PR 👍

From what I understand, you are adding functionality to automatically stage all files whenever a git hook is set

I don't think this should be enabled by default because one can have staged scratches and scripts that he/she donesnt want to include in my repository

Can you please share your usecase? Why not just create a git hook to stage all files?

I believe it could break Windows compatibility?
