git-exec-and-restage

Safely amend Git commits after applying auto-fixing tools

git-exec-and-restage executes a command for you on a set of files. This command may modify the files (imagine a linter in auto-fix mode, like prettier --write or eslint --fix). If the files were fully staged before the command ran, the changes will be automatically added to the Git index; if they were partially changed the Git index will remain untouched.
