Use a charset filter to make sure the data is written out in the charset

2000-12-05  Jeffrey Stedfast  <fejj@helixcode.com>

	* mail-display.c (write_data_to_file): Use a charset filter to
	make sure the data is written out in the charset it was meant to
	be in instead of UTF-8.

	* mail-format.c (mail_format_raw_message): Don't use the raw
	message body as the format argument, use "%s" instead. If the raw
	message contains %'s then it will segfault otherwise.
