Actually, after much tinkering with sshd lens, I have the gut feeling
that the problem is in the key_re lens. Looks like the '-' operator
between the 2 regex is not working properly.

Weird, the LANG change has no effect on my Rhel5 machine.

But it has an effect on my Debian machine... [scratching my head]

In fact, I can get correct results with setting only the LC_COLLATE
variable. According to the doc this variable changes the way character
sorts are done.

Yes, and there's still the fact that the problem cannot be reproduced
(so far) on a 32 bits arch.
