"plain" and "unambiguous" are usually not compatible notions.

I think the BSD, Apache, and Artistic licenses qualify under that
one.

Why should a license redefine what copyright law defines?

An author can *always* distribute patches under a license of their
own choosing, at least by my reading of fair use.  Also, it looks like
even if people modify the software for personal use, they have to publicly
post their patches.

That's not a copyright issue, it's a trademark issue, though the
copyright license can tie the use of that trademark to rights granted by
the license.
