emacs-unicode branch is not usable

[Dave Love]

Apparently random users have been advised to try the emacs-unicode CVS
branch.  I don't know why, but please advise against that, unless
they're serious about working on it.

It's in no fit state for users, who are quite likely to get corrupted
data, apart from redisplay problems and brokenness unrelated to the
basic Mule changes.

[To edit Unicode text, people should use Emacs 21, perhaps with the
patches I've published and/or Mule-UCS.  The ability to do that is
mostly orthogonal to the internal encoding (by demonstration).]
