more multibyte bugs

[Vladimir Volovich <vvv@vvv.vsu.ru>]

Hi Shenghuo,

with current cvs i'm able to send messages in koi8-r with CTE=8bit.
Thanks for good work! BTW, i wonder why sending via smtp worked fine
in prev. versions, and was broken in some recent one (and was fixed
without touching smtp sending code?).

With the current cvs version, there is one more bug that i just
noticed: open any message with 8-bit CTE, press TWICE C-u g, and then
get it again.  I.e. press

g
C-u g
C-u g
g

Then 8-bit text will be broken. Those multibyte problems are really
bad and tricky. :-)

BTW, as you agreed to use unibyte encoding for mbox, but you think
that it could be a disuster, i suggest to create a cvs "multibyte
cleanup branch" in which you could try to Do The Right Thing (TM);
i'll be happy to debug this branch and report problems. When
everything works fine, we could merge it into the main branch.

Am i right that mule will _by design_ interpret combinations of 8-bit
octets which form multibyte characters as multibyte characters in a
multibyte buffer regardless of the coding system settings?

In this case, it seems that ALL gnus buffers which are supposed to
contain arbitrary 8-bit text must be unibyte.

Best,
v.
