Historically, hooks are declared by placing an executable into
$GIT_DIR/hooks/$HOOKNAME (or $HOOKDIR/$HOOKNAME). Although hooks taken
from the config are more featureful than hooks placed in the $HOOKDIR,
those hooks should not stop working for users who already have them.
Let's list them to the user, but instead of displaying a config scope
(e.g. "global: blah") we can prefix them with "hookdir:".
