I've just installed these fixes:

2009-03-03  Kenichi Handa  <handa@m17n.org>

	* files.el (basic-save-buffer-1): Set car part of
	buffer-file-coding-system-explicit.
	(revert-buffer): Check car part of
	buffer-file-coding-system-explicit.

	* international/mule-cmds.el (select-safe-coding-system): If cdr
	part of buffer-file-coding-system-explicit is set, ignore
	default-buffer-file-coding-system and the most preferred coding
	system.

	* international/mule.el (set-buffer-file-coding-system): Set cdr
	part of buffer-file-coding-system-explicit.
	(after-insert-file-set-coding): Set
	buffer-file-coding-system-explicit to a cons.
