Interesting. And yet there's a bunch of Copyright.*Free Electrons in the
kernel. There's also this little mention on Wikipedia:

	"The droit d’auteur or authors' rights, in France, Belgium or
	Germany, grant (subject to some exceptions) the benefice of the
	right to natural persons (the author or his heir(s)) and denies
	it to legal persons (except for collective works, and for
	software), ..."[0]

Which indicates that for software this isn't true. Anyway, what I meant
to say was that it's unusual (at least in my experience) to submit code
authored and copyrighted using a corporate email address. So typically
I've seen people that work on open source in their spare time use a
different email address to separate these "identities".

But I don't mind this all that much, it just jumped out at me.

No need to do anything about it. I just think it's really, really weird.
