copyleft lite? - rev 3

[Bruce Dodson]

Thanks for the feedback so far!

By "without fee" I meant that <copyright holder(s)> were not imposing a fee;
this was confusing and unnecessary so I removed it.

I see what you meant meant about the "rights not specifically granted are
reserved" being superfluous.  I've removed it for now, but might add it
back.  Not sure whether the license is easier to understand with or without
that.

Nailing down the copyleft scope was the tricky bit.  This doubled the length
of the license terms.   As soon as you start talking about what's inside the
scope of copyleft, you also have to talk about what's outside the scope.  I
taken a stab at this but I think I could use some help with the wording,
especially in the last paragraph.

Here's the current revision:

<software program name>.
Copyright (c) <year(s)> <copyright holder(s)>.  All rights reserved.
