Modified to not encode space chars in the middle of a line. (isblank): New

2000-10-05  Jeffrey Stedfast  <fejj@helixcode.com>

	* camel-mime-utils.c (quoted_encode_step): Modified to not encode
	space chars in the middle of a line.
	(isblank): New macro if we're not on a system with the GNU isblank
	extension.

	* camel-mime-message.c (camel_mime_message_set_from): Reversed my
	changes, don't header_encode_phrase - it generates broken headers.
	(camel_mime_message_set_reply_to): Same.
