patch adding IUTF8 support to OpenSSH

[David Madore <david+bugs%madore.org@localhost>]

Attached is a(n absolutely trivial) patch that adds the IUTF8 terminal
mode (with code 42) to OpenSSH.  Prebuilt Debian packages for those
architectures I was able to build for, for testing and stable
distributions, are available in <URL:
ftp://quatramaran.ens.fr/pub/madore/misc/openssh-with-iutf8/
 >.

It works for me (transmits the IUTF8 mode when both the server and
client are patched, and, of course, does not break when only one of
them is).  I would love to see some independent confirmation, though.

I understand that the Debian maintainer's position is that this patch
will not be applied until the value is standardized.  So this patch is
submitted for testing purposes.

I have written a separate email to the authors of RFC 4250 to ask for
their guidance on how to get things moving on the standardization
front, although I fear a chickend-and-egg problem.  I am willing to
try writing an Internet draft if nobody else will, but without some
weight to back it up I'm afraid it won't go far.

Happy hacking,
