Unfortunately, I don't see a way for the user to call setlocale before a
Guile script converts the command-line arguments to Scheme strings, at
least not without providing their own `main' function in C.

It wouldn't be too hard to postpone the conversion until the first time
(command-line) or (program-arguments) is called.  That would change the
semantics somewhat, e.g. if the program modifies the argv[] array before
the first call to (command-line), but it might still be a worthwhile
change.

However, what should we do about scripts that use `-e'?
For example:

     #!/usr/local/bin/guile \
     -e main -s
     !#

     (define (main args)
       (display args)
       (newline))

I think we should consider decoding the command-line arguments using the
locale specified by the environment variables, at least in cases like
this where there's no way for the user to call setlocale before the
conversion happens.
