emacs 20.3 patch

[Simon Josefsson <jas@pdc.kth.se>]

This patch, by courtesy of Ken'ichi HANDA <handa@etl.go.jp>, should
(together with nnimap 0.87) make Emacs 20.3 handle eight bit
characters better.

I've not yet verified this, all christmas food is making me even more
lazy than usual.

	* process.c (read_process_output): Decide the multibyteness of
	string given to a process filter by a coding system used for
	decoding the process output.
