Well, we can easily take it to the extreme and make mdev call
the same script for all hotplug actions. As a nice bonus,
mdev.conf will be much simpler: just one line with script name ;)

It would work too, but I suspect no one would like it :)

I feel having device hotplug configuration smeared across
mdev.conf and a bunch of scripts (with two different formats)
is less convenient than having them in one place - mdev.conf.
