Fixes #612

@devcrocod Could you check the latest version of this branch on your mac?

I enabled the workaround for Linux too since we noticed the same problem happening there sometimes too. Plus, it doesn't hurt to run it if the problem isn't there.

I can confirm that chmod does its job, but i don't like how that hook works now :c I tried to commit just one file, but it added all other uncommited files and delay was quite evident too

I agree. It's mostly there so newly generated files are added to the git index automatically, because people forget. But it should mirror the commits to src only.
That said, that's another issue :)

This works for me. I don't particularly like this solution for aesthetic reasons, but it works.
