That indeed seems to do the trick.
I've done a little experiment and saw that when doing git reset the
hook gets called.
However, when switching branches the hook doesn't execute :(
I don't understand if it's intentional, since when I've moved to a new
branch HEAD pointed to another commit id.
The only workaround I see here is using the post-checkout hook in addition.
Thank you very much for helping me. I really appreciate it!!
