That's hopeless to keep track of across modules if something modifies
sys.argv or os.environ.

If the current scheme for recovering the original bytes proves
insufficient, what could work is a string type which can have an
attribute with the original bytes (if the source was bytes).  And/or
sys.argv and os.environ maintaining the correspondence when feasible.

Anyway, I haven't looked at whether any of this is a problem, so don't
mind me:-)  As long as it's definitely possible to tell python once
and for all not to apply locales and string conversions, instead of
having to keep track of an ever-expanding list of variables to tame
it's bytes->character conversions (as happened with Emacs).
