As buffer-file-coding-system is a coding system to use on
writing a buffer to a file, I think it's nonsense to have
different values in different regions.

I don't understand how buffer-file-coding-system is related
to that.  And, I think it's impossible to handle MIME
messages nicely without replacing the encoded data with
decoded data in some buffer.  Just displaying it may be
possible, but search/cut&paste etc. are impossible.

So, we have to decode the RMAIL buffer itself, or create a
separate view buffer that contains decoded text (as done by
Gnus).
