--encrypt-to usage

[Matthew Krotzer]

Hello,

	I've recently started using Gnupg and public key encryption
	in general. In my research I believe I've read that the
	--encrypt-to option is a bad idea because it creates another
	option for an attacker. If the attacker has either key,
	then they can decode what was sent to the recipient.

	Is the usage of this common and acceptable or should I avoid
	it like the plague?
