This is actually not right, there are 2 problems here

1. Running scripts/lint would lint all the files, and not the ones staged for this particular commit (I'd have to modify the lint script to take in a subset of files)
2. The lint script modifies the files. These files would have to be staged again before committing, ideally the hook itself takes care of restaging the modified files (if the lint script didn't fail).

If atleast 2. isn't addressed, there's no point in using the hook. I'll fix these and open pr for review again 😅

This is a good way for me to learn cmd line text processing (that's my justification for sinking time into this 👍)

The idea is to keep the linting fast enough that it's okay to run the lint on all the files, and not just modified ones. But, sure, you could run it on only the changed files.

yeah the linting is fast, which is really nice. Point 1 might not be a problem, point 2 is the main one.
