	In response to bin/5039, Christos added support to allow
	vacation to reply to messages that arrive with only an Apparently-To:
	header, or a Delivered-To: header. In response to concerns
	from me, expressed on source-changes (circa 19 April), that support
	was amended to do so via options, only.

	I believe that support continues to be wrongheaded. vacation -t A
	and vacation -t D will cause vacation to respond to mail it should
	never respond to, violating standards.

	My assessment is that the entire field of changes stemming from
	bin/5039 should be backed out. They serve no legitimate purpose,
	increase tool complexity, and have a significant chance of hurting

	revert the changes in question.
