[pp.int.general] Correct word usage for PP.

[Pat Maechler aka Valio]

I guess this definition has been taken from Richard Stallman's proposal
http://www.gnu.org/philosophy/words-to-avoid.html

But I agree with Maike: IMO goods are well defined - at least in the
economic academic discourse.
The term does not imply anything on tangibility nor on scarcity nor
whether these have to be sold.
Public goods include public parks, but also air or the sea.
I'd rather critize the term "digital" instead here...

Anyone who claims that "goods" have to be tangible lacks crucial
economic knowledge...
