OK, that is good to know. I developed the attached C program that does
the setlocale canonical test. On Debian Squeeze, I could not see any
change: if I pass en_US.UTF-8, I get en_US.UTF-8 returned; if I pass
en_US.UTF8, I get en_US.UTF8 returned. Can anyone test this and find a
case where the local is canonicalized? Run it this way:
$ canonical
LC_COLLATE = 3
LC_CTYPE = 0
$ canonical 0 en_US.UTF8
en_US.UTF8
We are looking for cases where the second argument produces a
non-matching locale name as output.
I have also attached a patch that reports the mismatching locale or
encoding names --- this should at least help with debugging and show
that a dash is the problem.

No idea.
