When I run Emacs as this:

% emacs --unibyte

Emacs doesn't start, but this error message is shown:
emacs: Attempt to set a constant symbol: enable-multibyte-characters

Emacs 23 doesn't has this problem.

We should remove the --unibyte argument, indeed.

I've checked a change into the trunk that makes --unibyte do nothing
(except for a startup warning).
