[Fontconfig] Problem with font languages in 2.2.90

[Keith Packard]

Please go back and read the message I posted a few days ago about this 
issue:

	http://keithp.com/pipermail/fontconfig/2003-July/000528.html

The problem is that you want both:

	en	"contains"	en_gb

and

	zh_cn	"contains"	zh

That way you can list both 'English fonts for Great Britian' and 'Chinese 
Fonts, regardless of territory'.

If we get some experience that this semantic is correct, I can back-port 
that part of the recent change (leaving out the other changes in Listing 
semantics) to the 2.2 branch.

So, we need some reports indicating that this is a good change...
