I have to think about this a bit.  
Complementing multichar folds is a weird area.

I think Perl doing full case-mapping is a feature.  And
sure it will still do it with functions.

I know that Java only does full CM on its equiv of lc/uc/etc.
It does only simple CM with its regexes.  

If Perl doesn't do full case mapping, does that mean we won't
be able to match "\xDF" =~ /ss/i and vice versa anymore?

I notice the pattern was forbidding the 128-255 code points,
which also pulled ANGSTROM SIGN and such.  But that one is 
ok since we have no builtin NFD matching to wrack our brains over.

I think I agree this should be a release blocker until we've
thought it through.
