Properly convert command-line arguments to UTF-8 on Windows.

Do the same thing we do for most other command-line programs - on
Windows, have wmain() rather than main(), convert the UTF-16 argument
lists to UTF-8, and pass them on to real_main(), otherwise just have
main() call real_main().  That way, they never pass through the local
code page on Windows.
