Subject: Why isn't there a hook for all operations that update the working tree?
Ævar Arnfjörð BjarmasonI have a repository where I'd like to run a program every time the working tree is updated. githooks(5) specifies that you can use post-{checkout,merge} hooks to hook into those two operations.
However that doesn't catch e.g. "git reset --hard". Is there any reason beside omission that there isn't a post-reset hook? Or hooks for any other thing (most of which surely slip my mind) which can update the working tree?

In principle, we historically tended to avoid hooks unless absolutely necessary. Even having to check to find out no hook needs to be run is considered wasted cycles.

I'd especially rather not to see a hook on something as low level as "reset". It would be too tempting to use "reset" itself inside a hook that is run from the post-reset hook, and I do not want to complicate the code even further to give callers to ask disabling the hook.
