Right. Git does not know that they are shell (or other) scripts; they
could be anything, and the advertised interface is that git will run
exec on them (and it is explicitly OK for them to exist but not be
executable, and git takes this as a sign that they are inactive).

If you are suggesting that git always execute them as "hooks/./$hook",
that might make sense if such behavior is widespread. But it sounds like
you are running a custom kernel patch to get around the noexec setting.
Here is the custom git patch to match it. :)
