Right, and they get their own bug reports about this (for example on
gnu.bash.bug).

I'd say we should add an option that turns on POSIX/i18n behaviour and 
defaults to `off' and documented like `currently this only
affects...'. I think its a case where not conforming to standards is
the right thing, reducing the number of (probably horrible)
surprises. Then we could think about adding the match-flags to turn
on/off the behaviour determined by the option for single patterns (I
haven't had a look at this match-flag code yet so I don't know how
hard to implement this is).

And later we can make the option control more things.

This also reminds me that the classes in match specs don't care about
the locale at all...

Bye
